Fuel Pump Leaks/Return lines/ FYI...

[davidkerryedwards]

Thanks for that tip. I've had a leak in the incoming fuel line that
increases when the engine shuts off. I had the line replaced and it
held for a few thousand miles then started leaking again. I'll check
the fuel return line. I think mine is much shorter than 2'.
