I AM BUILDING MY WVO KIT AND NEED INPUT. HERE IS MY PLAN. Two tanks, wvo with a electric pump, no switching valve but a check valve at the IP and a check valve on #2 diesel side. The LP #2has 7-9 psi my wvo pump has 20 psi. When I turn on the WVO pump the check valve will stop #2 diesel from being pumped and stop the WVO from going to the #2 tank. turn off the WVO pump and #2 pump takes over and run on #2. The only swithing valve will be for the return line. The WVO has a heated tank and the fuel line is ran insde a heater hose to and from the IP. I have heater wire to go on the injector linesIP to injectors. WILL THIS WORK?
