OK- two more questions to kick this dead horse with LOL. If I were to go with tow separate fule systems, I imagine I could put a T in the fuel line right at stock filter housing? And what kind of pump would be best to pump my heat WVO to the T.

Second (well actually third) question is, if I were just to T the line right before the fuel pump, about how much fluid is actually in the system from the pump to the injectors? I get about 13.7 MPG, so I want to know if I did T the fuel line there, how long would it take to burn all the WVO in the system.

Does a lot of WVO go into my fuel tank when I switch back to diesel?

Thanks!!!
