A friend came back to his home and pulled into his garage with the thought he was low on gas in his 1948 Mark IV 3 1/2 saloon. The fuel gauge is not operational, he uses a stick in the tank (which just barely showed a wet tip when placed all the way to tank bottom through the fill orifice at this time). When he tried to start the car a week later, the fuel pumps clicked but no start. On phone call to me I suggested putting a couple of gallons of gas in the car. No start and fuel pumps still click continuously. He then removed a fuel line at the pumps and tried putting a couple of cups of gas from that opening into the line heading back to the gas tank in hopes of filling the line going back towards tank and up to pumps. No improvement. I now have recommended he go to gas station a few times with his 2 gallon tank and get at least gallons in the car.
I’m not familiar with the inside of a Mark IV fuel tank.
1.) Does fuel enter above the tank bottom for the line feeding the pumps?
2.) Are there baffles preventing a 2-gallon fill from reaching the feed line?
3.) What is the minimum amount of fuel needed to restart a car which ran out of gas? Presumably the fuel sloshing when driving to empty could take the fuel level well below a minimum needed to restart the car when stationary?
