Hi Rick,

Yeah, I don't see any reason why you can't just leave the return line ports unused on that 6-port valve to use it like a 3-port one.

If you ignore the 3 unused return line ports, the valve should have two "inlet" ports on one side of the unit. And the single "outlet" port that goes to the fuel pump on the opposite side.

I mentioned earlier that I wasn't sure which style (1-wire or 5-wire) would be correct for your 78. But I just remembered a quick way you could check (assuming the dash switch is original). The 1-wire solenoid valves use a dash switch that simply flips between the two positions and stays where you leave it. The 5-wire motorized valves use a dash switch that is spring-loaded so it returns back to a center neutral position after you release it.
