    1950 DeSoto fuel pickup problem

    My car had pinholes in the gas line over the arch. It would run fine, but when it sat with less than half a tank of gas the gas would drain from the high point in the line and then the pump would suck air and not pump the gas. I had to pour gas into the carb to start it. Don Coatney told me to look for a leak in the line and when I pulled the rear wheel I could see that the line had been seeping gas, not enough to make a puddle. I replaced the entire line and in the process found a couple of more pinhole leaks that were buried in grease and gunk where the gas line goes under the front of the engine to the pump. Since replacing the line I have had no starting problems. Check the rubber line connecting to the pump also.

    1950 DeSoto fuel pickup problem

    Here's what a fuel sending unit looks like inside. This post also shows why they can have problems...
  4. I bought a brand new fuel gauge sending unit from one of the well known Pilothouse suppliers and decided to check it out with an ohmmeter before installing it. According to the supplier, the ohms for Pilothouse trucks should range roughly between 10 and 100 ohms as the wiper arm slides along the resistance wire. But all I got were completely erratic readings or no reading at all on my ohmmeter. I had purchased the part two years ago and the supplier wouldn't take it back so I decided to take the unit apart and see why it failed. There were two problems. First of all, the brass wiper arm was turned 180 degrees around and was making no contact with the coil of resistance wire! I turned the arm around to make contact with the wire coil. Second, the resistance wire was so loosely wound around the white nylon insulator that when the wiper arm moved up and down, the wire would move around with it! Because the resistance wire would not stay put, of course the resistance readings were totally erratic. Here's how I fixed it. First, I poked around on the loose resistance wire to try to space it out more or less evenly. Then, in order to prevent the wire from moving around, I got some crazy glue from Ace Hardware and dropped a bead along the bottom of the wire coil (opposite where the wiper arm contacts the wire of course). After that, I retested the unit and now get smooth variation from 10 to 86 ohms which should be close enough. I am not sure if most sending units work this way, but if they do, poor quality control in manufacturing can definitely cause erratic fuel quantity readings from brand new sending units. Is anything made with quality in the good old USA anymore?

    My hearty appreciation to the Webmaster for setting this Forum up, and more so for maintaining and sticking with it. I don't recall exactly when I first stumbled onto the site, it was while we were living in Carlsbad, NM, so it was before 2003, and you'uns have let me tag along through four States. Lots of good people, information, and stories here.

    1950 DeSoto fuel pickup problem

    I sure am interested in what fixes this. I have had similar instances where I show gas in the tank, but ran out. Fixing the fuel pick up tube flopping around in my tank, I thought solved my problem too. Until 2 weeks ago when I again ran out of fuel with a 1/4 reading on the fuel gauge. I have yet to fill the tank right up and see how much it takes. My fuel cap rubber seal is old and dry. Sloshing fuel will leak out if my tank is over 3/4 full. A new fuel cap is on the way now. Soon enough I will fill mine up and see. @busycoupe, if there were a pin-hole in the fuel line where it goes over the axle arch, would if not drip fuel when left sitting parked? This is new and interesting info.

    probably the best thing for back seat space is a lincoln from the 60s that used the retractable tech. The top was taken out of the trunk space that way.

    Check the fuel line, especially where it goes over the rear axle arch. If there is a pinhole leak there the car will run as long as the level of fuel in the tank is above the pinhole. But when the fuel level is low the fuel pump sucks air through the pinhole and won’t pump gas.

    "Ran out" of gas again. 11 gallons filled it up. So there is roughly 6 gallons in the tank when it goes empty. I'm thinking the entire fuel pickup has come loose inside the tank.

    Misses at higher RPM

    Contact pitting results from an out of balance condition in the system which causes the transfer of tungsten from one point to the other so that a tip builds up on one point and a pit on the other. The direction in which the tungsten is transferred gives an indication for correcting the situation. If the tungsten transfers from the negative to the positive point one or two corrections may be made. Increase the capacity of the condenser or shorten the condenser lead, If the transfer is from the positive to negative point, reduce condenser capacity or lengthen condenser lead.
