Finally got my AC fuel pump last night--went out before work this AM and started--fuel pump actuating rod kept slipping down--haven't put one in for many years--wished I had a set of mechanical fingers--I thought years ago we used thick grease--does that make any sense? Any ideas?

Thats the trick, use bearing grease on the rod and that will hold it up. Works eveytime

Put a bolt in the boss that is directly in front of the bolt, next to the side of the block. If you are old enough, you'll know the small blocks used in 55-57 chevys used motor mounts on the front of the motors. Obviously for years now the mounts have been on the sides.

But the bolt boss directly in front of the pump pushrod, was originally the top bolt of the motor mount on that side, in the original sbc casting. Pull the bolt out that is in the hole and replace it with one that is an inch longer than what is there, and it will hit the pushrod. Tighten it a 1/4 turn or less once it hits the pushrod - just enough to hold it in place.

There is a bolt hole on the front of the eng in line with the push rod that should have a short bolt in it, take that one out and use a longer bolt to hold the rod up while you install the pump. You might have to bump the eng over to rotate the fuel pump lobe on the cam if it is in the way before you lock the rod in place with the bolt. I found that grabbing the rod with a set of needle nose pliers was the best way to get it slide up into the eng.

Thanks--now I just need a "sure fire" excuse to get out of work and go home--any more good suggestions?

The first time I did a fuel pump on a Corvette, looked the situation over & pulled the right front tire & used long extensions. Have posted that tip many times. Esp. for A/C.

:cool:

Replaced mine about three weeks ago, used the grease method. worked fine for me. I also replaced the rubber gas line hoses while I was there. The littls "S" hoses are some times hard to find at your local auto parts store. Ordered mine from Zip.

:iagree: Fevre is da man. Just don't forget to replace the longer bolt with the original shorter one. :nono: Another method that works well is to apply some axle grease to the pump rod to hold it in place. :cheers:
