87 tank selection valve?
(acting like it is trying to run on rear tank, which doesn't work)
wouldnt restart without priming carb.
Now it wants to stall going uphills or after running for a period of time (like plowing)
BTW 1987 F250 4X4 351w ho 4BB
I have allready replaced the mechanical fuel pump,and carb now im thinking the selector valve is s###ting the bed for good.
Any suggestions??????
