I have never had good success rebuilding fuel pumps. Maybe it is just me. I consider myself pretty handy at fixing stuff, but never had much success with pumps.

Having a clean work area and a way to keep the parts aligned really helps. So does following the instructions to a T.

The reason they quit supplying parts for that early pump was because the cost of the labor to repair them was more than the cost of a whole new pump. At least, that was the official reason given back then, in a different time.

Personally, I find that rebuilding the square style pumps to be a PITA. If the person doing it is a pro in the shop, at normal labor rates, the original reasoning still applies. Some other pump styles are so simple and well worth repairing.

I agree Frank R. They are a pain getting everything lined up and keeping springs in place. I don’t mess with them anymore.

they are not bad if you read 3 times and understand the instructions

work on a clean surface
glue the little mushroom caps on their respective springs with a touch of crazy glue

next step is to glue the springs on their nipples (plastic) to keep them from flying away to nowhere ….with a touch of crazy glue

pile the layers and reassemble do a blow test when done

Frank, who was it that showed us his jig and step by step procedure for building the little pumps on the old site? I don’t like to build them either, but that was a pretty impressive setup he had. Just one of the many things we lost off the old site.

A couple of the extra screws which come with the new coils and have their heads removed can be used to make a little fixture to help keep everything where it should be while working on the pumps.
