Figures, it's an 85. So, if I get a fuel pump "Pigtail" for a 86 up, the Delco will plug right in ? Are there any "Changes "I need to make as to the Fuel "LINES" ? or will the 4 cyl lines be able to be connected to the 3800 with steel line and compression fittings ? It's a 4 cylinder now. Thanks
I would get a fuel sending unit pigtail harness (in-tank portion) from an 87-88 V6 car. That way you know you are getting the right one to work with the new pump.
All you really need is to cut the fuel pump connector off of an 87-88 sending unit harness and splice them into your existing sending unit wiring. I use the red butt splice crimp connectors that have the heat shrink+glue already on them. I have found these hold up just fine inside the fuel tank environment. Any good auto parts stores should have them.
Your stock sending unit lines may have a plastic pulsator that couples the steel line to the fuel pump. Remove this and discard it. The new fuel pump you buy should come with a section of rubber hose and clamps that you will install between the sending unit's steel line and the new fuel pump. If you do not get a section of rubber hose with the fuel pump, you must buy fuel hose that is rated for in-tank use. NAPA Auto Parts has this hose and it is expensive. The spec for this line is called: SAE 30R10. You only need about 2 inches of it.
I also suggest you perform the fuel pump "hot-wire" mod I have explained on my webpage here: http://www.gmtuners.com/fiero/hot_wire.htm
