Do I have to buy an aftermarket fuel rail to run an adj. FPR on my car? If not what all do I need to put one on with the stock fuel rail?
just buy a fuel return line kit and it will have everything you need. http://www.modernperformance.com/product_info.php?cPath=174_270&products_id=1547&osCsid=c5a02b6b619f487d518029cbc248a2c2 you don't need an aftermarket rail.
Aaron from realtune sells them on here he has really nice kits i know alot of people who has them and i wish i was one of them
you need either a aftermarket rail or a 03 rail to run the aaronneon kit as the regulator is after the rail. the agp kit has the regulator before the rail, so you can use your stock rail.
