Sorry to barge in on this thread but I'm am about to embark on a similar issue.
My wifes 73 has 2 tanks. Has the switch on the dash and a solenoid valve down on the frame.
Its the 3 port valve which has to be 1 port from each tank and 1 to the pump.
The Switch on the dash is what switches the sending unit signals to the gauge correct ?
So when power is applied to the solenoid valve it switches from right to left ? (Its running off the left tank now and the gauge doesn't work).
I need to make sure the valve is bypassed (which I think it is) and then check power to and from the switch and down to the valve.
Should be Left tank first and then switch to right hand tank once the left is empty ? I want to make sure I hook it all back up correctly.
