Article Title: Fuel Pump Replacement
Contributed By: shojuan

If you are going to be dropping the tank then after getting the fuel level low enough that you can fit the remainder in some gas cans you have laying around then you can slip a piece of vinyl hose onto the outlet of the fuel filter, route that into your 5 gallon gas can and then ground the fuel pump test pin on the EEC-IV test connector

with the key in the ON position and the fuel pump will pump fuel as long as you're holding the other end of your test jumper on a chassis ground. The lighter you get that tank the easier your task will be.

I went the "cut the trapdoor" route using the writeup that Crazy88SHO wrote last winter and didn't have any problems. If you use a tool that makes very shallow cuts (I used a dremel cutoff wheel and went no deeper than the actual metal) then you should have plenty of clearance between your cutting tool and the fuel lines on the passenger side (I remember about 1/2-1" of clearance...which can make doing this very dangerous for somebody who is clumsy when cutting metal and/or using a clumsy cutting tool).

Either way, the kit you are going to get will have the replacement filter sock. It WON'T have a fuel return line check valve (that little orange "duck call" shaped deal on the fuel return pipe next to the fuel pump on the fuel pump/fuel level sender assembly.) It's up to you whether you want to replace that. Get one at the dealer if you decide you want to replace it. Change your main fuel filter when you are done too. Good luck!
