Rotate the engine and watch the function of the pushrod..
There are two different styles of pumps and two different pushrods, if the rod and pump do not match the pump won't function. Also some pumps today have opposite functioning inlets and outlets, you may have the fuel lines attached backward to the new pump.. The cams don't wear... They are part of the dizzy drive pinion |

While we're wating on pics, here's my buddy's dual cab restoration.
http://www.classicvws.com/dblcab.htm He found it in a fire station's parking lot in Sweeden, had it shipped to the US for the restoration. (IMG:http://www.classicvws.com/images/bludblcb-1.jpg) |

If you attempt to use the short throw pump with the long pushrod, you'll be needing another new pump. The Cap'n

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. |

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. The Cap'n |
