I have ordered a fuel pressure regulator from Advanced Auto parts and it was just a stock one. Any way it looked like the right one from just comparing it to the old one that is still on the car. So I start taking off my fuel rail and get the old one off and they gave me the wrong one it is just a little to big. Now that I got my car back together and able to drive back down there should I just try to order a new stock one and take the chance of it not fitting or being the wrong one again. Or should I order an after market one. there was a Holly one that was $128 would that be a good price and good idea.

Thanks for the help

 

The holly one is good.
I have this one FPR, it's a cover with an ajuster thing, you have to reuse the internal parts.
