Question - schematic shows a 16ga black wire that powers the fuel selector valve. If a new electric pump is installed, is the wire big enough to power the valve and the pump in the AUX position? Or do we run a "sister" wire, or a whole new wire? Coach has no house batts, so no relay set up back there...

16 ga. will handle both. My electric fuel pump draws about a 1.4 amp and I have a 3 amp in series with it that has never blown.

John,
Never use the rear power source for your engine support.
Not a bad idea to use a switch with an light to advise you when it is on.
Naturally when you turn the key off, it will go off if connected to the
correct source.
