Re: Fuel lifting pump making noise when first starting engine
A thought... GMC's with unit injectors pump an immense amount of fuel back to the tank to cool their injectors,Little engines do the same but more discreetly. If your system has a short closed loop to save running a return line back to tank any heat or bubbles or crud stays in the loop
