Hey guys and dolls (Margie and ??)...I thought my fuel pump was not turning on after running for a while due to some heat expansion issue....then it died again after just running to 3-5 minutes...hmmm? So my college friend of 50 plus years who is a VW lifer and has one incredible 914 that he built from scratch suggested today that it is the fuel pump itself? Mentioned some sort of solenoid or something in the fuel pump...I certainly don't know....anyway the logical test is to test for power to the pump when it stops running....if there is power then it is the pump....if there is no power then the problem is upstream from the pump. Just wanted to hear from the pros out there...thank you very much and I will be under the car tomorrow....
All the best, gg |
