Pollak 6-port selector valve
This video is a demonstration of improper functionality of the Pollak 6-port selector valve I purchased for my 89 F150 to convert the dual-tank selection from vacuum to electric. The issue demonstrated is that applying the voltage to the valve and then inverting it does not change the position of the valve. It appears to require a voltage drop to 0 for either a) and extended period of time or b) and internal ground otherwise not provided by my truck's setup to allow it to correctly switch. Instead, I purchased a different brand valve that functions correctly when the voltage is inverted.

so how would I do this on my truck? I'm not an electrician, so I'm a little confused. I have port A set up to my right tank and port B to my fuel gauge and port C set up to my left tank, but I only get a reading on my right tank.

What truck are you working on, and what is the selector switch in the dash like? This was for my 89 F150. I used to stock selector switch which is a DPDT switch. So one of the poles fed fuel gauge and the other pole fed power to the in-tank pump. This way, when I switches, both the circuitry for the signal from the tank and power from the tank were switched together. If it's only a single-pole switch (SPDT), then you will not have any way of switching both the pump and the sender.

Tristan Lee 1976 Chevy C20 . it has a 5 port switch, one is ground one is main power and one goes to the fuse box. under the truck it was set up so one wire sent power and I think one went straight to the tank? so I'm pretty confused.

Unfortunately, without seeing how everything is currently wired, it's hard to say what's necessary to wire this selector valve up on your truck. My F150 had a vacuum-style selector -- meaning that all the switch inside the cab did was change power to the 2 different pumps. Depending on the line pressure coming from the active fuel pump, the diaphragm in the selector value would mechanically change ports to allow fuel flow. Since I upgraded to the electrical-style valve, I ran all new wiring to the pumps and selector valve, and had to do additional wiring under the dash involving not only the DPTP switch, but also a relay to invert the polarity of the power going to the selector valve which causes it to change its position. You can find pictures of how I did everything here (www.ford-trucks.com/forums/1431138-need-help-hooking-back-up-dual-tanks-2.html#post16278620) though it may not benefit you much with your truck.
@tristan....what is the brand and model # of the valve that works correctly.

This was the one I ordered that worked correctly for my setup: www.amazon.com/gp/product/B0049UCF82

DUDE! "Since I don't have a DPDT switch...." is why your thing ain't working. That's why they provide a MOMENTARY on-off-on DPDT switch. This is a MOV (motor operated valve) not a solenoid. A momentary switch will, by its very nature provide that 0 volt break between switching. There's nothing wrong with your valve....at least there wasn't before you gave it voltage in one direction for prolonged periods...that's not the way it's designed, man. You're like the kids and women who cook power window motors by ramming them up and down by holding the switch too long.

Sorry, that isn't entirely accurate. For this particular case, yes, I had the wrong valve. The valve originally on the truck required continuous voltage. This Pollak version was not. I ended up returning it for www.amazon.com/dp/B0049UCF82/ref=cm_sw_r_cp_apa_fabc_KH7BKGEXWH7K7T386WK4?_encoding=UTF8&psc=1
