I have read in the manual that if the fuel temperature goes past a certain point the sensor will cause the ECU to run richer. Not really sure why , since warm fuel atomizes much more easily.

This is how see a a FPR, it is like a band aid of sort. An example, say you have 550cc injectors but your setup (MODS) is good for 590+rwhp. People will install FPR to make the 550cc injectors work like 600cc (Not scientific but you get the point?) If you do it the right way you would upgrade the injectors to 740cc so you don't have to worry about adding a FPR let alone if one fails while your at WOT.
Most people that use them can not get a hold of the right cc injector so they get the FPR to compensate.
So you can do it the right way (above) or if you want to save on some money get the FPR.
I'm a Z32 guy and we do not delete the fuel temp sensor because it will affect the engine performance. Think about what you said above?

That is because heat will detonate your engine. If your surrounding enviroment is hot the fuel will get hot as well. That temp sensor tells the injector to run richer so you do detonate. Do you get? It's there for a very good reason.
Also what size injectors (cc) are you running?
Here is a link on what they do.
