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.

I'm not gonna argue with you , but suffice it to say it doesn't make much sense. I spent several years in the hot rod community before I turned to imports , and fuel temperature was one of the least things we worried about. Hot fuel atomizes much more readily , and is more desirable than cold fuel for that reason. Also , all fuel injected cars have an FPR , so I don't understand you saying one is not desirable? Ever heard of FPR overrun? That's what happens when you have too much fuel pressure and volume and not enough recirculation capacity , it causes the injectors to run much richer than they are supposed to. A higher capacity FPR is an absolute necessity for high powered sports cars. I've also seen FPR failures spike fuel pressure to very high levels , depending on how it fails. And I don't see how keeping an undesirable temperature sensor can hurt performance , instead it would HELP , because the engine would not be forced to run richer than it is supposed to. Fuel temperature often has nothing to do with engine temperature. Given where the fuel lines go under the vehicle , the inclusion of even a 3" exhaust and a large cat can heat up the fuel lines and the fuel inside.
