Fuel heater- Good or bad idea?
I was thinking about how fuel temperature affects MPG and power. I came up with the idea of heating the fuel rail on a returnless system with engine coolant to possibly help the fuel vaporize more completely. If that would work, what would the ideal temp be? I don't really see a disadvantage to heating the fuel besides maybe making knock slightly more likely, but I do not know that it would help either. What do you think?
