Review on 🔧 ACDelco U7000 Professional Fuel Tank Selector Valve: Enhanced Performance and Reliability by Mario Beckwith

I used it to switch between two tanks in my 1975 IH Travelall. The valve has two independent connections - 3/8" and 5/16". Since all my fuel lines are 5/16" in diameter, I used them and plugged in 3/8". I use a mechanical fuel pump so I don't use it to select electric fuel pumps. Just use two wires with a DPDT reversing switch. According to the manufacturer, there is a filter after each tank before the selector valve. It also provides good visual control of flow.
