Auxillery fuel tank selector?

[hogasm]

I am installing an auxiliary fuel tank in the bed of my 06CCLB. I want to be able to use an up fitter switch to control a fuel valve that will allow when fuel can gravity feed into my main tank.

What is a good 12v valve to use?

I like the greasecar valves. You can pull them apart when they get jammed up due to not installing a screen in front of them. It should work well with a uplifter, they have a default position and only move when 12v is applied.

Another option would be a pollak valve. You will need to supply 12v for one direction and -12v for the other. That wouldn't be hard to do but may require a bit of creativity with relays if the uplifter is on/off single pole. These valves are sealed so you can't fix them if they get stuck.

I have a polak valve in the garage. Will it allow the fuel to gravity feed into the tank or will it need to be pumped?

You could make it work. Assuming it's a 3 or 6 port valve, you will need to cap one end off.
