Default Replacing the fuel pump

What is the best way to do this in a '79? Should I just pull the motor? That thing looks like it is extremely difficult to get to.

I've already attemped it from the bottom and gave up.......Iread on here that it's easier to get to it by taking the wheel off and going through the inner fender hole. We'll see.

:iagree:

Take the right wheel off and go in through the fender well with a long extension. Don't forget about the fuel pump pushrod. You need to lock it in place before removing the pump.

It's real easy to do with the wheel off. I'm a novice mechanic and did it in one afternoon. You just need the front jacked up and the front right wheel off.

:lol: Sounds like your A/C compressor is in the way Stoge. I just replaced mine without the compressor installed (yet). If the wheel well trick dosn't work try to unmount and shifting the compressor first before removing the engine. Its just that when I take off too many parts on these old cars it seems to snowball on me and end up rebuilding most of the car. :yesnod:

Moving the A/C compressor was a thought that I had, too. I think I will try the right wheel trick first. I have the new pump and new "S" hoses. If I remember right, there is a hole you put a bolt in on the side of the block that holds the pushrod up so you can get the new pump in. Isn't this directly above the fuel pump on the block? I have an extra 350 in my garage I guess I can use for reference.

I just took my a/c off the mounting brackets and set it out of the way as far as possible with the hoses still attached. I did mine from below and from the top. :cheers:

Yes there is a hole on the fuel pump casting but on the front/water pump side of block. You can see the fuel pump push rod through this hole. But you need to use a bolt long enough to reach the push rod to hold it, then remember to remove/replace it once the new pump is installed and plug hole with shorter bolt. I just used some thick greese (assembly lube) on the push rod and it held long enough to bolt everything together. Discovered I had been missing this bolt since purchase of car probally leaking all the time.
Just be careful with those small 1/4-20 bolts as I snapped off the head of one. Used a torque wrench too. Broke an easy out next. Spent days a drilling away with an 90 degree angle drill to fix. :nopity

Rather than using a bolt to hold the pushrod try putting grease on the shaft. That will hold it in place long enough to put the pump in place.

:iagree:

You might also want to turn the engine over (by hand) to make sure the fuel pump cam shaft lobe is NOT on the "bump". Installing the fuel pump when the lever is under compression is more difficult.

[I just replaced mine without the compressor installed]

Oh yeah..I don't have a compressor on my 79. I wonder what happened to it.
