Noisy Fuel pump on M38A1

Post by Vanguard6 » Wed Aug 06, 2014 6:53 pm

Now that I have fuel going to the carb and it is running pretty decent. I have a very noisy lower half of my fuel pump. Has any one else experienced this? It sounds like a vacuum leak but I have checked all of my connections and Teflon taped the connections on the pump. I can put a stethoscope to the engine and it purrs like a kitten when I put it on the connection for the fording air on the lower fuel pump bowl it sounds like an iron lung pumping air. Thanks for any/all assistance
