My new mechanical fuel pump is not pumoing enoug gas to the carb to keep my bug running. I have tried two pumps and still have the same probklem with apparent fuel starvation. I pulled the line and started the car and get just a trickle of gas. I measured the height of the pump rod and it is a shade under .5". I am assuming this is likely the problem, but the pump rod is brand new. Did VW make two different lenghts? I am running a Brosol Mexican fuel pump, the alternator type I think, vs the OG German type with the servicable filter. If all pump rods are the same what could I do to fix this? I was thinking of removing some of the material on the pump base.
