The fuel temp sensor is there to help prevent vapor lock. At a certain temperture the ECU turns on a solenoid to the vacume line to increse the fuel pressure and the boiling point of the fuel. At the same time the ECU goes to a different program to lean the mixture to compensate for the higher fuel pressure. This only happens on hot restart.
If you take the temp sensor and the solenoid out, then the car will run slightly lean for a few minutes after a hot restart. Usualy you will just see some minor drivabilty issues for a few minutes after a hot restart. If you hit boost, the ECU will turn this lean condition off so it's not dangerous.

Apparently mines not working anyway. Still vapor-locks on 80+ degree days.
