Know this before you dig in, so you'll know what to look for
Tank switch is a single pole, double throw
When the switch relay coil is NOT energized, the valve has one tank line opened to the carb.
When the switch relay coil is energized, the valve switches to the other tank
Electrical gremlins had my dash fuse blow often...after...buddy who owns a speed shop build a custom 350 (Edelbrock Performer dual plane intake, Performer 4 barrel {should have kept the quad, liked it better}, 280 cam, 3 angle grind SS valves, ported/polished/CC matched/flowed heads, shotpeened anything ferris, forged rods, TRW pistons and a few other things forgot) and had his wife's cousin (who couldn'd get a job anywhere else put it in...he shorted and blew the fusable link...so every so often the dash fuse would blow
First time...took a while to find the right fuse...there after, knew...but it would blow the spare quickly
Since the un-energized tank was empty, no fuel
Learned to use the energized tank, run it dry...then switch to the un-energized tank and drive home with no dash lights
