This part# is for gasoline engines only and your VIN indicates you have the 6.5L diesel engine. You would need to test your low side fuel pump after the lift pump to see if it is supplying the high pressure injection pump. If you need the lift pump it is part# 25117340. ( Support )

Can I get a diagram for the wiring on the fuel pump ( Joel crawford , 06/28/2017 )

I want to ask how the fuel gets to my generator with this fuel pump 25178125 2003 workhorse chassis.
What are the 3 lines coming out of the pump?
I assume sending, return and generator?
My generator line is plugged after running a couple hours and my coach bogs down going up hill.
Want to make sure this supplies fuel to the generator as well as the coach
Thanks
Dave ( Dave Grier, 01/17/2017 )

Hi Dave,

The fuel is not supplied to your generator via the engine fuel pump. The generator has a fuel pump mounted on it with a suction line that runs into the fuel tank. The three ports on the engine fuel pump are for feed, return and evaporative emissions. Generally if your fuel tank is at 1/4 tank or lower your generator will not pick up the fuel as they don't want you to run the fuel tank dry by generator usage. The best way to diagnose if the fuel pump is your engine performance issue would be to hook up a fuel pressure gauge at the fuel rail on the side of the engine. I would contact your generator manufacturer to inquire about the fuel feed and fuel pump system for it.
