I have to replace the fuel pump and the rubber Gas lines on my 76, it looks like a nightmare to get at the pump and the lines just looking from underneath the car. Anyone have any tips or advice on how to go about getting it done? any recommendations on a replacement pump that has the original configuration?

I DID MINE ON MY '76 AND THE HOSES WERE EASY (BUY PRE-BENT ONES,USING A PIECE OF CUT GASLINE HOSE WILL KINK.), BUT THE PUMP WAS A BIT OF "KNUCKLE BUSTER" GETTING THE BOLTS IN. I CALLED A BUDDY OVER AND HE WORKED FROM THE TOP, WHILE I WORKED FROM THE BOTTOM AND IT WENT IN PRETTY EASILY.
GOOD LUCK,

kstyer said: Lift the front of the car. Remove the right front wheel. It really opens up access to the pump. |
or use ramps
When you get the right wheel off, go in OVER the control arm. Some long extentions and you can get right in there. Almost easy.
Just another note. When you pull the pump off there is a fuel pump push rod that operated the pump. The front of the cam pushes the pump push rod.
The rod will likely slide down, making it almost impossible to install the pump.
First, you want to make sure the pump rod is all the way up. You can push the rod up and turn the engine. The rod will reach a top peak, and that's where you want it. It's the easiest postiton to install the pump. Other wise you need to compress the fuel pump spring to get the bolts started. That's a pain.
To keep the rod from sliding down, there are two things you can do. One is to remove the bolt on the front of the block that lines up with the rod, and gently install a longer bolt to hold the rod in place. When done remove the longer bolt and reinstall the original.
Method two is to remove the rod and coat it with wheel bearing grease. The thick grease will hold it in place on a cool engine. A hot engine will thin the grease and it won't hold. The small quanity of grease disapates when the engine is started, by melting and blending with the oil. The engine will never know the difference.
If you can't get the rod up due to the fuel pump mounting plate, just remove the plate, install the rod. Just be sure not to tighten the plate bolts before either starting the fuel pump bolts (with or without the pump) or at least make sure the holes are lined up before tightening the plate. If it's crooked, the fuel pump bolts won't go in.
