I hadn't thought about the electric pump not flowing if it is off, that would explain alot. It is a Carter 5000, too much power actually but when I start running WVO I will need it. I re-plumbed it again tonight bypassing the mechanical pump and used my pressure regulator. It was worse because the pressure regulator apparently won't work on over 8 psi. I don't understand why but after I opened the package it said not for fuel systems over 8 psi. When I turn on the pump nothing comes out. I can take it off and blow through it but apparently the extra pressure shuts it off.
I plan to leave it bypassing the mechanical pump because the electric is supposed to be better for the WVO so I guess tomorrow I will go shopping for a better pressure regulator and see if that is my problem.
