Re: I want to convert to WVO and need plumbing diagram of valves etc
I don't know of a schematic available, which is a bummer. I think better when I can look at a map first.
A couple of guys have given reports on how they plumbed their trucks... search for them in this forum for tons of information. In essence, you are creating a by-pass loop of coolant to go through some sort of heating coil in the veggie tank and running beside the fuel line in order to heat the veggie prior to burning.
As for the valving, most put a solenoid/valve between the diesel tank and the lift pump. That way you can choose whether the lift pump pulls out of the veggie tank or the diesel tank. I'm planning on adding a pump on the veggie tank to help with the increased viscosity.
As for the return, I'm still unsure as to how the PSD is plumbed. Does the return line go to the tank or is it deadheaded in the engine? Some use a 6 port solenoid so that when on diesel the return diesel goes back to the tank and when on veggie the return veggie goes back into the fuel lines heading toward the engine. The idea here is to keep circulating the same oil so it will get hotter.
I'm thinking of returning the surplus veggie back to that tank just as we return the surplus diesel. Opinions wise diesel fans?
I look forward to reading replies to your question as I'm still learning too.
