Hey y’all if anyone can help me I will be forever grateful. So ingot this old truck from my uncle as a gift it has high mileage but was still running Great. About two months ago after having a rear driverside blowout is when it all started. what was thought to be bad gasket on the fuel filter cap has turned into a new mechanical fuel pump s well as sending unit. The fuel bowl is still not filling up or only does on ocassion. Everyone and a while I’ll start it drive itround and it’ll actually drive for the day but most days can only make it around the block. The aux fuel tank or tank 2 has a bad sending unit and is missing the fill line. The regulator seems be pressurizing as specified by ford. Please help I’m not a mechanic I just want to drive the Öl girl!!
thx yall,
Pat

 

Rig up a jerry can. Milk jugs work great for this. This will take both tanks and switch out of equation for now.

I recall 3/8" feed and 5/16" return. I would buy a few feet and then dump in half a gallon of No2 into the jug.

Crank it from under hood to see if the pump is pumping...if so it should be squirting back out the return hose into the new 'tank'

If it does, start that boy up and let it run for a while. You may still have mechanical pump issues. If so, trash it all and efuel the truck.

 

If that return fuel is bubbly, frothy, or cloudy looking, the pump is probably pulling air somewhere. Suction leaks, vacuum leaks, can be very difficult to find, sometimes.
