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)

The generator pump (below) requires the longer push rod. Note the actuating lever is higher up inside the pump body (on the bottom)

The alternator style pump uses the shorter push rod. As the Cap't mentioned, you use the long rod with this pump and you'll get one good pump and it'll break on you. Note how the actuating lever actually comes below the base of the pump body. On this pump the upper nipple is the INLET and the bottom nipple is the OUTLET (it's the opposite of how you would logically think they should go).

Hey Nate, Is that Brazilian stuff good now or is it "still" crap like in the late 80's and early 90's? If I recall correctly, the parts pecking order went German, Mexico then Brazil. I'm in the need to know cause I'm trying to convince someone to sell me their early bus.
