FSE should be fine mate! You'll obviously need a gauge as well as a fuel rail adaptor.
You will have a rail adaptor in then mate. Its the bit that connects the FPR onto the stock fuel rail via rubber hose. Like this:
Mine is a MINES one, so is purple. Yours will be silver I'd imagine!
Is your FPR already fitted then mate? If it is, whoever fitted it will have had to put a fuel rail adaptor on in order to connect it to the fuel rail (although I think you can keep the stock FPR in place, but doubt they did that.)
Gauges can be bought off eBay for fairly cheap - you can either get one that screws directly into the FPR, or an inline one that goes in the fuel hose.
I can only seem to find the gauges that read up to 1bar? will i not need one that will read over 3 bar?
