2002 Tahoe 5.3 Fuel Pump Sign In


I have a 2002 Tahoe 5.3 non flex fuel and the pump was letting air in at 1/4 tank levels. So I purchased one at auto store and set out to do the change.

Question is when I got the existing one out and opened the new box. There's a issue at the fuel line connections!

Existing has two metal connections

New pump has two plastic (with a third stubin the middle).

When I called the store they said I have the wrong pump, the online info says it will fit all!

I have no way to get to the store to do the exchange with tank out on the ground. Please tell me if I the new will work and what do I do with the center stub if it will work.

Thanks for the advise!!

There are 2 different pumps. One is for "robust fuel system" and one without. If you have the wrong pump, it has to be exchsnged.
