changing fuel pump cam in 1600 dual port, what do i have to do(old VW content) Options

[pete-stevers]

My old 59 single cab has a 1600 dual port engine ..and I suspect the fuel pump cam is gone...but what do i have to do to change it?
i bought a new pump already
fuel from tank is fine
spark is good
no fuel coming out the carb side of the new pump
push rod has little wear
(i have little aircooled exp, cut my teeth on water cooled)

Actually, there are early and late "generator" pumps. Early ones take the long pushrod, later ones the short one. The "alternator" pumps are canted over like the one pictured, and they always use the short one.

Another thing to look for is whether opr not the pivot pin is locked into place. The old pumps had circlips, the late manufactured ones don't, and the pin slides right out after a few weeks or months. Bad news. The last one I bought had a "fix" designed. Unfortunately, I forget what it looked like ................. I've been hitting the ends of the pin with the mig welder.
