before i can get my car dynoed/tuned, i need to get a fpr and maybe a fuel rail. Do i need to get a new fuel rail or will a fpr hook right up to the stock one? If i need a new fuel rail does anyone know where i can find one that has a fitting on it where i can just plug a fuel pressure gauge into it. Thanks guys
 
does that fpr come with a fitting for fuel pressure gauge or do i have to modify my rail?
 
You should check out Slowboy. They have CNC machined fittings along with various kits to modify your fuel supply. I got a full tank to rail setup along with a FPR kit. Everything is pretty self explainatory in terms of going to AN fittings but know this, if you're going to get an upgraded FPR, you MUST upgrade your return line as well .The stock return line is too restrictive for an upgraded fuel pump (which I assume you have if your getting an FPR). At some point I'll probably write a tech article but until I do, just know that you should use metal brake tubing (I believe it was 3/8th inch) and run it in the stock location.
 
A lot of people love this kit by Import Evolution. It includes an Aeromotive FPR and has all the parts to hook it up. It's a one-stop solution basically.

It also has extra fittings for a fuel pressure gauge.
 
The Buschur modified SX AFPR is a direct bolt on to the factory 1g rail. A little expensive but it takes about 15 minutes to install and is extremely easy to regulate. Or you could get an adapter that bolts onto the factroy rail and use a universal regulater but make sure that it compensates for boost 1:1.
 
Yeah, doesn't work for our cars. Cannot adjust down and I don't believe it is even a 1 to 1 pump (not positive on this point). Go with the Aeromotive from Import Evolution. If you are worried about install, get their install kit.

DON'T get the B&M kit. It is simply a modification of the stock regulator and doesn't give you the flexibility you want and need. Pay the extra money for something like the Aeromotive FPR, it's worth it.
 
Do you still have the 190LPH fuel pump? If so, why do you need an AFPR? I thought the 190 wouldn't overrun the stock FPR.
