My new fuel pump arrived for Patterson, so I tossed the old one (which was a glass bowled hand-me-down from Chris McKay back in 2017) and installed the new one. Of course, the new one didn’t work. So, I did the usual over a period of a few days:
I checked the lines, I recheck the lines. I rechecked the rechecked lines.
I checked the clamps on the line. I installed different clamps.
I checked the cam for a groove or signs of it being worn (none that I could feel),
I reinstalled the electric pump to double check the lines and to check there was enough gas (there was and it worked).
I pulled the new pump and hand pumped it with some gas in a container (to prime it). It pumped by hand fine. I reinstalled the new pump, but no luck.
So, I pulled the old pump out of the trash (which had worked fine until late last year), reattached the fittings, and hand pumped some gas out of a small container (that worked).
With the old pump primed, I reattached it. The pump is now working.
That was a lot of work for little progress!!
