Installed a new fuel pump on my recently rebuilt 261 and after starting the engine noticed that gas was streaming out of the small vent hole on the bottom half of the pump body. The engine ran for about 1 minute before I caught the leak and shut it down. Aside from getting a new pump Im really concerned about gas getting into the oil thru the pump body somehow?? The oil does NOT show signs of contamination such as an increase in oil level or a gas smell in the oil. Can gas get into the oil thru the pump??
