Tank Selector

[mankypro]

So I'm about to wire my 12v in-line fuel line heater. I want it to be on whenever I'm on my rear tank.

The question is - is the circuit open or closed when the rear tank is selected?

I could so this with a test light I guess, but I figure someone here might know...

I thought you were running the HotFox. Isn't it on all the time- I mean, there's always coolant flowing thru, where does the 12v come into play?

I'm installing a hotfox in the rear tank and a vegtherm mega in the engine bay.

If I understand correctly, those silly troublesome electric fuel-selectors only have power DURING the switch from tank to tank, just like an electric two-speed axle.

Which is probably why the one under my truck looks like it's been there for 26 years

If not powered all the time, you'd think it would last...

So if this is the case, looks like I need to wire a toggle switch and just flip it on when I switch to my rear tank.
