Inside the fuel pump are two one-way valves. They are plastic discs (Moss,
Key #6 in the diagram. N/A). One of them could be defective allowing
gasoline to circulate through the inside of the pump. I had the problem on
a trip many years ago. I solved it at the time by cutting a disc out of the
plastic from a blister pack of something. It worked and is probably still
in my back-up pump that I carry.
