Hello. I have a 91 Isuzu 4x4 pickup with the throttle body v6 in it. The
fuel pump recently quit on me. Now the problem I am having is the fact that
they (part stores) want almost $400 for the fuel pump. The fuel pump is
located inside the fuel tank.
I was wondering if I could install an inline high pressure fuel pump up from
the tank and get away with it. This will only run me a little over $100. I
disconnected the fuel line just before the filter and could get a steady
stream of fuel . Fuel line lower than the tank therefore just siphoning the
tank. This tells me the fuel pump in the tank is allowing fuel to pass
through. It will not kick on and add any pressure.
Thank you for your thoughts on this.
i dont see why the aftermarket pump wont work, but have you tried
shopping around for an in the tank pump? the one for my rodeo was
just about $60 for the pump only, (not the complete assembly)...
P.S. if you decide to try the inline pump you probably should make
sure to get one that provides the proper pressure, on my 93 3.2 mpi
the book calls for 46-48 psi, should be pretty close to the same on
yours, but be sure and check...
