Re: 1973-1991 Dual fuel tank systems theory of operation
Nice writeup. I bought a switch and valve for my 81 because the right tank will fill when using the left tank as the draw even though my fuel pump only has 1 inlet and one outlet to the Holley. It baffles me. But now I can check the wiring and hoses when I replace them.
If there are return lines at the senders i was thinking of running a hose up high to a fuel filter as a breather. I might have a charcoal can on one of my parts trucks that I can use instead.
