I have had to bleed air from the fuel filter of my 1986 CUCV for the past couple weeks and have narrowed the problem to the fuel filter base. I replaced the fuel pump (not the injector pump), Fuel filter, and pressure tested the fuel line from the tank to the pump. The only issue left is a fuel leak from the base that the fuel filter is fastened to which is attached to the fire wall. I havent taken it off yet but fuel appears to be dripping from someware on this unit. Are these prone to problems??? It has some sort of foam covered sensor in the front but other than that I cant see any potential for leaks. Will check back for messages.
