Hey guys, any suggestions on how to rig a fuel selector for an auxilary tank? Its custom fit, and I was thinking of a 6 port selector from a Ford or Chev with two tanks. Also trying to figure out how to have fuel return to the tank it was pumped from when I switch tanks on the fly. Thanks for any help!

80 -90 ford dual tanks switch feed and return just by which tank is pushing fuel. Two lines from both tanks go to it. two lines go to the engine to supply it. The in tank pump is what makes switch. But you would need to make sure the pressure wasnt to high.

Pollak 6-way is readily available. It has 2 source inlets to 1 engine feed, 2 recirc inlets to 2 recirc outlets and will even swap 2 tank sensors to 1 fuel gauge.

Google Pollak fuel valve or go to JCWhitney.com

The 73-80 chevy pick-ups used a solonoid 6 port valve. the 81-87 chevy pick-ups used a motor driven 6 port valve. The motor driven valves were better. The ports were 3/8 and 1/4 hose barbs.
