Solving Vapor Lock in my 1960 Lincoln Continental Mark V

Vapor lock can be annoying and frustrating, to say the least. Coupled with Ensign Murphy’s law, vapor lock will always occur at the worst possible moment. Even many mechanics don’t fully know how to approach the problem. I don’t recall ever having seen an in-depth article on the subject, although there have been some good suggestions in Lincoln and Continental Comments in the past.

Can vapor lock really be cured? We will not confine ourselves to just Lincolns and Continentals in these tips, since the same basic cause and cure apply to every gasoline-powered car on the highway. Vapor lock is caused by only two factors: too little fuel pressure or too much heat. Either causes the gas in the fuel pump and line to boil, creating vapor. Also, modern-day blended fuel containing ethanol tends to vaporize more easily.

Figure 1

The place to start is to have a mechanic take a fuel pump pressure and volume test. Four pounds minimum is a rule of thumb, but check the spec for your car. If the car is an older one, hand the mechanic a 3/8” or 5/16” clear plastic hose. If you can see bubbles, it indicates a fuel line that is rusted through. Also, have the mechanic check the fuel filter, radiator, fan belt, fan shroud, and fan clutch (if used). You should also consider a fan with more blades that will pull more air.

Many cars, including some Lincolns in the 1960s and some Chrysler products, have a vent system to prevent vapor lock. If this is plugged or disconnected, fix it. If you correct these items as needed and it still vapor locks, you may have to install an electric fuel pump near the gas tank with a control switch on the dash. This will cure many vapor lock problems, but I didn’t want to drill a hole in my dash, so I started looking at the placement of the fuel pump on the 430 CID V-8. What a strange location indeed, with the pushrod-operated pump, set high and forward on the engine, was repeatedly praised by auto writers at the 1958 previews. On first inspection, it seems to be an ideal location; it is certainly very serviceable and easy to replace.

Except anybody who has had a 1960 Lincoln vapor lock on a hot day will immediately understand the folly of putting the fuel pump in direct line with the hot radiator air. This vapor lock problem became more pronounced after 1961, when the under-hood space became even more restricted. The use of a pushrod should also have been recognized as a potential source of failure, following Ford’s experience with them on the original flathead V-8s. So why was the fuel pump put way out there?

According to former LCOC member Jim Crabtree, at an Edsel Owner’s Club meeting, he met an engineer who worked on the development of the 430 CID motor. This man answered many questions, but most importantly, he solved the fuel pump mystery. It seems that in 1952-1955, when the 1958 engines were being designed, the staff was told that all cars that were slated to use the 383/410/430 engine had been approved for electric fuel pumps built into the gas tank. At the last minute, the bean counters at Ford nixed the electric pump idea and insisted upon a mechanical version. The problem was that by the time the order came down the block, the design was already finalized, and there was simply no place to put a mechanical pump. Last minute re-engineering led to the high mounted, pushrod-operated, “breakdown waiting to happen” approach. The engineers knew all the potential problems, but placing the pump where it is required redesigning only the cam and front cover.

Figure 2

In the end, the bean counters were happy, but nobody else was. So, if chronic fuel system failures cause you to add an electric pump to your car, relax in the knowledge that this was how it was supposed to have been anyway.

Again, I didn’t want to drill a hole in my dash for a switch to operate an electric fuel pump. I began looking for an alternative solution while still keeping the car factory-original. What I found was a new fiberglass heat sleeve by Thermo-Tech. (Fig.1) The company has been around since 1986, and its belief in Thermo-Tech products has made it the number one source for heat-management solutions.

In my 1960 Lincoln Continental Mark V Convertible, there is a 3/8“ diameter rubber fuel hose, approximately two feet in length, that runs from the metal fuel line up front to the fuel pump itself, which needs protection from excessive heat. So, I ordered the following:

QTY:1
Code/SKU: 17063
Product Name:  Thermo-Flex Sleeve
Color: Black
Size:  5/8″ x 3ft
Price: $23.50
SH: $5.00
Grand Total: $28.50

The rubber fuel line that needs protection is 3/8” in diameter. Sliding the 5/8“ Thermo-flex shield sleeve over the rubber fuel line makes for a nice and snug fit. By ordering three feet of the flex sleeve, I had one foot left over, which I then used to encase the metal fuel line from the fuel pump filter to the carburetor. (See Fig. 2) Since installation, I have not experienced another vapor lock issue. What a great find for only $28.50!

Recently I had a near-catastrophic occurrence with my 1948 Mercury Convertible’s fuel system, which is very similar to my 1941 Lincoln Continental fuel system. One afternoon, I drove my car hard up the mile-long road to our home and parked it in the garage attached to the house. The next morning, my son come over for coffee, and after raising the garage door and coming into the kitchen, he said: “there is gasoline on the floor in the garage.” My reply was that “all old cars smelled after being driven.” He said, “no,” I went and looked, and there was a large puddle of gasoline that had flowed from the engine area out from under the car. There was a large freezer less than four feet from the pool. I opened the other garage door and turned on a fan to blow the fumes out of the garage. I then used paper towels to absorb the gas that was not under the car. Looking under the car, I did not see any gas dripping. I called my expert old car mechanic, and we agreed a carburetor leak would not have produced such a large amount of gas overnight. Looking in the engine compartment, there did not seem to be any evidence of a leak.

Because of the pooled gas under the car, the Mercury had to be moved outside. Using a heavy rope attached to my truck, I pulled it out into the driveway. Since the driveway is up a hill out of the garage and with the front of the car pointed downhill, gas started dripping from around the engine oil pan onto the pavement. I put a container under the engine and cleaned up the garage puddle. inspection under the car revealed gas coming from the oil pan, where the oil tube attached. The gas was floating on top of the oil in the pan. The Mercury’s fuel pump is attached to the oil filler tube. It was clear that the rubber diaphragm inside the pump developed a tear. The auxiliary electric fuel pump had helped force gas into the oil filler tube and then into the engine. I have used non-ethanol gasoline since I’ve owned the car, but the previous owner had used ethanol gas, which is destructive to older rubber products. Our Lincoln’s stock V-12s don’t have an oil stick, and gasoline in the crankcase cannot leak out. However, some owners have converted their cars to Ford V-8s, so this is a genuine possibility for them.

My expert mechanic had an engine explode and burn. A similar scenario that caused that disaster had also happened in my Mercury. A new mechanical fuel pump should be rebuilt with ethanol-resistant components. You may reduce your chances of a catastrophe by using only the electric fuel pump and bypassing the original one. If you continue to use the mechanical pump, replace it if you have used ethanol gasoline. Turn off the auxiliary electric fuel pump when not needed, and pray this will not happen to you and your car. I am blessed I did not lose two vehicles and my home.

Old Car Massacre in Georgia

Old Car Massacre in Georgia

It took about 35 years for over 230 Lincolns and Packards (and parts) to be accumulated. But it took only a short time for all these cars and parts to be loaded on a slow boat to China. Right now, as I write this, many are coming back in containers full of barnyard fence posts, gates, barbeque grills, brake rotors and calipers, fenders, axles, and ad infinitum. The Lincoln genes still exist in the molecules of many new steel products stamped “Made in China”.

Several years ago, a story was in Continental Comments showing Bennie Bloodworth’s Lincolns resting on his 67 acres in Lutherville, Georgia, which is 60 miles south of Atlanta. Now they are all gone. Many of our fellow members’ cars are running and showing with parts from Bennie’s land.

This past April, my wife Jan and I spent a week with Bennie to help him organize the “crushing” massacre of these cars. We actually wept to see a 1969 Mark III being reduced to 12 inches in height. (Rusty 30s and 40s Lincolns much less.)

Bennie ran ads in LZOC and LCOC publications and Hemmings for over a year offering rock bottom prices for parts and whole parts cars from $100 each to about $300 each. There were not many takers. Due to his health, Bennie had to sell his land. But it had to be cleared of all cars, parts, automobilia, by June 3, 2004, as a contingency of the sales contract. Now Bennie has one Lincoln, a 1941 Continental Cabriolet, totally restored, that he bought in 1957 as the second owner.

Salado National Meet, April 23-26, 2009 a Resounding Success

Salado National Meet, April 23-26, 2009 a Resounding Success

The first National LCOC Meet to be held in Salado, Texas, was successful beyond all expectations with 64 cars exhibited or judged and over 200 members and their families attending. This was the first time the spring Texas Regions’ meet has been expanded to a National Mid-America Meet in the 21 year history of the event and it was awesome.

Salado is a spring car tradition in LCOC in Texas and preceded the first LCOC Mid-America National Meet, held in Fort Worth, Texas, in 1989, by a year. Over the years Salado has attracted approximately 40 cars every spring at Blue Bonnet time, but this year 64 cars set the record. The meet is always at the historic Stagecoach Inn and this year the inn was booked to the max and the dining room was packed to an overflow for the Saturday night Awards Banquet.

The four-day event began Thursday, April 23 with the registration desk opening and dinner on your own. Nothing was changed from the regional format according to LCOC President Glenn Kramer who said that Salado has always been kept simple, informal, fun, and relaxed.

Friday was mechanical judging and a tour of sorts which was actually a scavenger hunt on Salado back roads with members doing the tour on their own.

Friday evening was the traditional cocktail hour and barbecue at Don “Doc” Ellis’s City Garage a few blocks north of the hotel. Former LCOC President Doug Mattix and his wife Carol of Rowlett, Texas, were on hand both Friday night and Saturday. Doug and Carol have not been present at LCOC National Meets in recent years due to Doug’s health problems with his back and legs, and it was good to see him back.

Saturday the area in front of the hotel was awash with cars, so much so that cars overflowed down the entry street and into the trailer parking lot. There was only one car that did not show up, a limousine from Minnesota owned by Gordy Jensen, but six other Minnesota cars did show, most of them driven the 1,200 plus miles from Minnesota to Salado.

The traditional LCOC Awards Banquet Saturday night was altered somewhat in keeping with the Salado tradition. Members dined in the main dining room of the Stagecoach Inn. After dinner everyone walked across the hotel grounds to the Conference Center where the awards presentation was made. At the awards presentation there was the addition of a People’s Choice Award which is a Salado tradition. That award went to John and Dorothy Palmer, Bamum, Minnesota, who drove to Salado from Minnesota in their 1946 Lincoln sedan.

Charlie Steward from Florida did not quite get the Hard Luck Award even though he took two rocks in the windshield of his 1994 Lincoln Town Car. Charlie received the Drive Tour Award. The Hard Luck Award went to Bruno Hernandez with a 1969 Lincoln Continental Sedan. The Long Distance Award went to Harvey and Marie Bane who drove their 1958 Lincoln Continental convertible 1,439 miles from Martinsburg, West Virginia.

The Elliston H. Bell Founder’s Trophy was awarded to Bob and B.C. Hardisty, Southlake, Texas, for their beautiful Taos Turquoise 1956 Lincoln Premiere convertible. This is the second time that a 1956 Lincoln convertible has won the Bell Trophy.

All in all, it was a great meet, reminiscent of LCOC meets of the fifties and sixties. A full report on the Salado Mid-America National Meet will be carried in the September-October issue of Lincoln and Continental Comments.

Walking the Night

Sometimes, the night is just better. I’ve written about my love for driving after dark, a passion that dates back to my earliest days behind the wheel as a teenager over 35 years ago. I’m equally fond of nocturnal walks. My neighborhood is the perfect place for such forays: secluded, yet well-lit for safety. I can make a loop in about 40 minutes. It is the only exercise that I actually enjoy, so I do it several times weekly.

Physical health is not the only reason you might find me on foot after dark. Oftentimes, it is required to maintain my mental health. If you go outside to check on your Lincoln one evening at one of our meets, you might find me walking the show field.

I formed this habit a very long time ago. In 2004, I was in my sixth year as the director of the Indiana Region of the Cadillac & LaSalle Club. That June, we hosted the annual Grand National in South Bend, Indiana. As I recall, we had over 200 cars and 600 people, which was large for the time. I was the activities chairman for the meet, so there was a lot of stress trying to ensure that everyone had a good time and that as little as possible went haywire. In the evening, I would go down to the parking garage where most of the show cars were parked. Sometimes, I’d ride along with our security guy, a retired police officer, as he patrolled the garage and grounds on his golf cart. Other times, I would walk the same route in silence. It was a way to unwind and forget about the stress of the day.

From that day forward, I made it a habit to walk the show field, usually after the evening’s events had concluded. Today, I find that it is even more critical. While I enjoy our LCOC National Meets and CLC Grand Nationals, I am, by nature, an introvert. I make it a point to get out of my comfort zone by riding with or dining with different people as much as possible. While it is wonderful to meet new people and see old friends at these events, sometimes, it is just too much stimulation. I need to take a little time to collect myself and refocus. At that point, it’s time to grab my walking shoes, put on some music, and see what awaits outside.

 

The 2025 Eastern National Meet was a prime example. Like the Mid-America National Meet three months earlier, it was a great time, with lots of wonderful cars and equally wonderful people. I had visited this same hotel in June 2024 with the Cadillac & LaSalle Club. During that event, I saw very little other than the hotel grounds, not once leaving them between Tuesday and Friday. I do appreciate the somewhat looser schedule of LCOC Meets, where there is a little more room to breathe between events. That said, the Awards Dinner is a hectic time for me. National Chief Judge Dan Staehle reads the winners while John Walcek captures them on film for the Lincoln and Continental Comments. My job is to make sure the name matches the photograph. After the dinner concludes, John has the top award winners pull their cars under the front portico for more pictures.

This saves a lot of time on Sunday morning, but this does keep us hopping until 10:00 p.m. Considering that I’d been running since the Judges Breakfast 15 hours earlier, I was a bit spent by this point.

With my duties concluded for the night, I made a beeline for the show field. As it was pretty late, I needed something mellow to listen to, so it was mod-revival rocker Paul Weller’s post-Jam project, The Style Council, pumping its blue-eyed soul through my earbuds. Many cars were covered and others were already loaded onto trailers, ready for an early Sunday-morning departure, but there was plenty to see. A pair of mid-1950s Premiere Convertibles. A trio of 1970s Marks. A lone Mark II. A slab side convertible. The car that I most wanted to see was still there—Paul Willson’s 1940 Lincoln-Zephyr Continental Cabriolet. As readers of this column know, 1940 is my second-favorite year for the Continental, right after 1963. I had enjoyed talking with Paul earlier about his car. There is something magical about the combination of street lamps and moonlight on these cars. I photographed it from every angle, allowing the limited illumination to create a study of light and shadow.

Some time later, I found myself sitting on a bench, not far from the hotel’s entrance. I’d put the appropriately titled “Walking the Night” on repeat and then just soaked in the sounds. Sunday would be a long day, requiring me to cover 650 miles in under 11 hours to get home in time for dinner. When I awoke the next morning, I was refreshed and ready for the journey ahead, thanks in part to the previous night’s nocturnal stroll.
