Can a stock fuel pump produce too much pressure?
I didn't put a gauge on the line. I thought that maybe with two carburetors showing the same symptoms that maybe the pump was pushing too much pressure.
It looks like this:
No cast in identifying marks, just the ink printed marks you see here.
I changed to another one that looked similar.
Delphi?
It started and ran fine…. Then started puking fuel through the inside of the ThermoQuad.
It was the same as with the other pump.
Once the fuel evaporates, the car starts up fine and then floods over again. I ran out of time to try a known good carburetor.
The threaded fitting on the pump that feeds the carburetor has a leak. As I tightened the line, the pump body twisted a bit.
Two pumps, same symptoms.
I'll put the first pump back in and try a carburetor from another car.
