Is there a point?
Is there a point to put an aftermarket fuel pressure regulater on before the fuel rail? I know the stock SE fuel rail has a built in FPR so does that mean I have to remove that one??? I got an aftermarket Rising Pressure Fuel Pressure Regulator and am wondering whats the difference between rising pressure and a norm FPR.

If the built in FPR fails, injectors will not function at too high of a pressure. It'd be a good idea to remove it, if you install a aftermarket FPR. The difference between a Rising FPR, and a normal FPR, is that as vacuum deacreases, or boost increases, the pressure will increase in a rising FPR, whereas a normal FPR will keep the same pressure no matter what.
Rising FPR's are normally used in turbo cars because the car requires more fuel as more boost is built....boost enrichment.

Run one of those cheapy Y-vacuum fittings from Pep Boys or something......I doubt you'll want to use that FPR on a n/a car though. The pump will take care of the FP plenty.

It was given to me with a package of other parts. Since its just laying around, its cheaper than buying another regulator.

I'd just leave it as stock for now. No sense on putting in something that you really shouldn't use. Sell it on ebay or something, and get a standard regulator.

I run a Carter 255lph @ 95psi shut off with a stock regulator on my SE and have had no problems whatsoever. The stock regulator is set for 71psi IIRC so you should have no problems out of it handling anything you put on.
