Fuel lines

watercat - whats the fuel pressure in your lines??? i was looking at boiling points at different pressures for fuel and at i think it was 39psi you can barely hit 180 degrees without vapor locking so if your not at that high of pressure it's not going to work!!!

Don't mess with it, I've tried it, it didn't work, nor was it safe. The reason was is that there are 14.7 molecules of air and 1 molecule of fuel in simple terms, it's much easier and more effective to heat up air than fuel, and safer.

I did research a while back about gasoline boiling point, and it's very complicated as is, you ad pressure to that and you're looking at a very complicated system that is not very safe, especially if you have return fuel system on the car.

thanks for reminding me about the problem with return lines, i forgot because my jeep only has a supply line no return cause the pressure regulator is on top of the pump at the tank and i hit 45-49 psi in the fuel line, so i should be able to add a fuel heater without any problems i think. the problem with having a return line for though's who don't now is that the fuel goes back to the tank at 180 degrees so that the tank hits 39 - 40 psi if the tank can't handle the pressure it leaks or worse case it blows, either way is bad because if the tank can more then handle the pressure you'll usually spring a air leak and loss fuel fast, if it can't handle the pressure it will probably do the same as before and leak like crazy anyway
