Re: Fuel Pump Replacement

Should be 3 lines on the top of the module all with quick connect fittings. Lube the O ring with engine oil and push them on until they click.

1/4" is fuel vapor going to vapor canister.
5/16" is fuel return from the regulator.
3/8" is pressurized fuel going to the injectors.

Post some pictures that show what line you're having trouble with. The pump kit that you bought... did it come in a box labeled "AC Delco"?
