Fuel Pump

Well I managed to get the fuel pump taken apart. I found there are differences as to what was in the kit I ordered, to what was inside the pump. The vacuum section diapham plate center holes had to be drilled to 1/4 inch in size to accept the new threaded push rod.

Also the existing valve cages are a one piece design. The kit came with brake style rivets to use to re-secure the cages. But since the cages in my pump are a one piece design where the cage and the center rivet are fused together, so I couldnt use the rivets from the kit. Those cages are just pressed in place. So I just reused them.

The vacuum values where in good shape and the rubber still soft, so I left those alone. Those valves are very hard to get out and replace. So the instructions in the kit recommend that you only replace them if needed as reseating the freeze plugs can be a problem.

I should have it all finished tomorrow. I took a ton of pictures and will be posting a how to article for those wanting to rebuild their own pumps.

I found that the bottom of the fuel pump still had old fuel in it and had the remains of various tiny insects. Not sure how they got in there as the diaphams where in good shape. Maybe they got suckup through the tank. Perhaps the tank sock is long gone.
