FarmerJon Posted January 13, 2022 Report Share Posted January 13, 2022 I had the fuel pump in my coupe peter out at the end of December, so I ordered a rebuild kit. Due to holidays and shipping delays, it showed up yesterday. Eager to get my car running again I had already stripped, cleaned and prepped my fuel pump, so this morning I started dropping parts in. Immediately I saw that the one way valves were a very poor fit. The old ones were press fit in, making them a bit of a trick to remove. The new ones are around .003-.004 smaller than the holes, so they have nothing to retain them. I tried to stake one in, but it is impossible to displace enough material to press the valve down into it's gasket to seal. Am I doing it wrong? Should I apply some sort of sealant or adhesive to the valve, then stake it? Open my second pump and see if they fit better? Pretty frustrated, I was hoping to have the car running enough to get it under cover before the next snow coming, as it died in my open driveway.

FarmerJon Posted January 13, 2022 Author Report Share Posted January 13, 2022 I got it. Had to fashion a sort of seal driver and swage them. Now they fit snug. At the expense of my pride, I will leave this up, in the case someone else has the same issue. 3 Quote Link to comment Share on other sites More sharing options...

FarmerJon Posted January 14, 2022 Author Report Share Posted January 14, 2022 A 1/2 socket fit one. A few solid taps with a hammer and it got much tighter. A few more and it expanded enough for a good seal. For the other side, the socket wouldn't fit over the frame of the valve, so after a thorough search of my work, I found a junk collet that fit over it but had a thin enough wall to only press the edge. Due to collets being fragile I opted to use a shop press on this one. Again I went a little ways, stopped, and checked. Then applied pressure again. I don't know if you could crush these things, but didn't want to find out. You can see collet ended up breaking while I was using it, but was able to hold it together enough to finish the job. A dedicated tool would be easy enough to make, may even be able to find the right size tubing. 2 Quote Link to comment Share on other sites More sharing options...
