at least with fuel injection, we could track fuel temp and get the fueling back in-line after some trial/error.
oil..... i don't think this would introduce that much more heat into the oil?
hot fuel that isn't moving would likely vaporize at the pressures a MPFI system runs at..... i imagine the simple solution behind that would be either a microcontroller that turns the fuel pump on and runs it for a few seconds at a time and repeats that a few times(either a set number of times or until fuel temp drops below x *F) or perhaps going really simple and setting up some 555 timers to just run it for a while after the ignition is off.
