highly doubtful.... you'd basically have to have heated up the entire tank of fuel.

Here IS a problem I've seen with EFI and the higher fuel pressures..... is when someone creates a VACUUM situation with a fitting (not pressure). Fuel boils with VACUUM... (it's not really boiling - it cavitates).

I'd be looking for a RESTRICTION in the fuel system.
