Short Supply
: Over the past two years I have been having fuel supply problems with my 1953 M38A1 jeep. When I firs. got the jeep about 10 years ago I did a complete fuel system cleaning and parts replacement. This included a new fuel tank, filters, sending unit, fuel pump, and I overhauled the carburetor myself.Everything was fine until about two years ago. The problem is that when the jeep is not started for three or more days I have to prime the carburetor to get it started. Once started it runs great and will restart daily as long as three days have not passed. Since this problem has come up, the fuel pump has been replaced twice and overhauled once. The fuel pump now seems to be working correctly as it provides 4.2 lbs. of pressure at the carburetor and holds pressure there. Vacuum and pressure measurements for the fuel pump are within specs. When the jeep will not start after the three-day period, I can loosen the fuel line at the carburetor and the fuel pump is supplying plenty of fuel. Recently, I drained and cleaned the fuel tank, installed a new in-tank filter, an in-line filter between the tank and the fuel pump, and an in-line filter between the fuel pump and the carb. Last year I had the carburetor
