Pollak, 6-Port Fuel Selector Valve
Genuine 'Stoneridge Company U.S.A.' Pollak Valves
Incorporates six ports including return ports, designed for use on dual-tank fuel systems for selecting the tank from which the fuel should be drawn from (and returned to)
These motorized valves are driven into position by an electric motor and are stable in either position. They only draw power for a fraction of a second during transfer. A switch in the valve shuts off the motor when the valve reaches the selected position, it then does the same in reverse when power supply is reversed across the terminals using a suitable switch (DPDT On-On)
Complete with wiring connector and installation manual, YOU WILL ALSO NEED A DPDT ON-ON CHANGEOVER SWITCH, AVAILABLE HERE
IMPORTANT - The pollak valve can only be used with clean fuel, that is FILTERED TO 10 MICRONS, and in a liquid state. Failure to observe these points will result in either 1. Dirt building up on the pistons, or 2. Solid (frozen) fuel preventing the piston from travelling - both will result in immediate failure of the control circuit which will burn out. Failure of this nature is outside of warranty and so must be avoided

If using in a vehicle running on SVO / WVO you should also be using a Heat Exchanger to heat the fuel entering the engine, this will help to prevent pump and injector failure. Below an example of a suitable product for this application.
