I read all the topic, but as my native language is not English I had trouble understanding few things.
So to conlude (correct me if I'm wrong):
there are two types of FPR:
1. with the constant fuel pressure
2. with rising rate fuel pressure

Q1: As I understood the 2nd type is better than 1st one, but didn't understand whether 1st type is any good at all? does it give a noticable difference?
Q2: Are these on Ebay for 30$-50$ any good? what are the differance between FSE any Ebay ones? Are there any risks on buying cheaper ones?

Q3: (talking about NA engine) Does FPR really forces more fuel into the engine? I mean if ECU sees more fuel entering, doesn't it shortens the opening time of injectors (I don't know how to exactlly explain it in english :/ ), resulting in less fuel (less meaning the same amount as before) entering the engine?
