Re: Fuel Pump Leaking

I am getting much longer than 5 years out of my fuel pumps, but I never use any fuel additives.

Why don't you run the car a few minutes and observe the pump. I am guessing that is not gas as it would not rest there for 3 days, it would evaporate. The only way for gas to get there would be if it were coming out the vent on the neck of the pump. You will see and smell that pretty quick. I see evidence of oil leakage in the vicinity of the pump, running down the engine block.

On the Rochester carbs, the stuttering you describe can easily come from a very small piece of dirt in one of the passages in the throttle plate.
