Just replaced fuel pumps in both tanks in a 1993 f -150 and it still is loosing fuel pressure. It takes a while for it to crank it. But once it cranks it runs good. What the crap is wrong?

Fuel pressure regulator, leaking injectors, crud in the fuel lines.

We replaced the regulator also. My husband and son are thinking the fuel line between the front tank and going to the motor.

Does it have dual fuel tanks? If so check the switching valve, it may not be switching properly and venting pressure back into the return system.

Yes sir it has 2 fuel tanks
