if any one else has a 12v/coolant combo set up i'd love to hear what order you put things together in- i have a 12v inline fuel line heater (like a vegetherm) and am adding the FPHE and i think an electric boost pump... coming from the fuel tank, which order should the heaters & pump be in? i realize once the engine is up to temp, it probably doesnt matter much as the FPHE will be getting me good WVO temp, but since im starting on wvo as well, i'd like to make sure im getting the most heat from the 12v heater- so maybe i should put that one last in the chain, right before the lift pump?
