Bad fuel pump

huntnwater · November 18th, 2009, 12:50 AM

On a 93 5.0 I only have 10 psi at fuel rail. New inline fuel fliter no change. Fuel pump bad??? Can i leave the old pump in the tank and put the inline pump in between the tank and engine. My question is, will it pull fuel through
the original pump that is bad inside the tank?

a fuel pump change is easy, empty the tank, disconnect lines, drop it, change pump, reassemble, get a walbro 255

do not try to leave your old pump in there while running an inline

I'm not sure it's the fuel pump. I changed inline filter. It only has 10psi at fuel rail. It will start while spraying gas into engine with squirt bottle. We are gonna swap this motor into a 68 Mustang so I didn't want to replace the pump in the tank. I want to put a inline pump that can be used when we do the swap. If this is even the problem??
