Has anybody ever tried heating the fuel in the fuel line for better atomization and a less dense fuel charge?
I'm not talking about extremely high temps. I wrapped my fuel line on my old Hyundai Accent a few years ago with heater hose that had hot coolant going through it and it seemed to help a bit while cruising on the highway. It took a while for it to get warm enough to help though (returnless fuel system).
diesel block heaters warm the coolant(to keep the thick oil moving faster) . some extreme cold areas they install warmers in the fuel tank because the diesel fuel will gel up if cold causing no fuel flow.
