Seriously double and triple check it there's plenty of guides online on how to tell fakes.

Look at the people who have advised this and there join dates and post counts.... We've all seen more happy go lucky people super happy with there bargains on "geunuie parts "and the follow up thread when it all falls to shit.

If your running the stock ecu but really want to run an aftermarket fpr, then a safer way of doing it is to leave the stock fpr in place and plumb the new fpr on the return side. Set its base pressure to the same or slightly below as the stock fpr. That way the stock fpr will still maintain all the standard idle/cruise/low boost fueling before the second reg kicks in as boost inceases, raiseing the line pressure higher than what the factory one would which then pushes more fuel into the injectors and richens things up. This way even if the second reg craps out you have some fuel still happening from the factory reg.



As above thou, genuine is best be it Tomei, Sard, Turbonetics etc. Malpassi maybe as a last resort (they have a tendance to lose a psi or two of fuel pressure over time and need constant monitoring/adjusting.
