Fuel Pressure Regulator help.... I am currently puting an LQ9 based 6.0L in my 95 Trans Am. I want to keep the fuel system as a return style system. Does anyone have any suggestions on how to do this or what fuel pressure regulator to buy? I'm kind of in the dark. I know the general idea of what needs to be done, but I want to make sure I know some specifics before I start.
Thanks in advance.

You can use the stock fuel pressure regulator/filter from a 1999 to 200? something vette. It is a combination filter/regulator and is cheaper than buying an aftermarket regulator. If you do a search you should be able to find pictures and the part number.
curious but if you run the vette filter/regulator on a stock lets say z28 ls1 with the dead head regulated rail. will the regulator on the fuel rail still work? reason i ask is i found several differnet other car fuel filters that have returns on them like the corvette filter with the same sized return and sending line but slightly smaller out tube.

The only fuel rail setup that is "return type" is the early C5 (1997)
After that, all the fuel rails are "deadhead", they only have one line going to them. This includes the Z28 rails, and all the truck rails.
The 'vette filter regulator is a pretty simple, cheap, easy piece. It has 3 ports, fuel in (3/8"), fuel out to engine (3/8"), and fuel return to tank (5/16"). Its inexpensive ($40 or so at most any parts store) and provides the correct pressure (about 58psi, assuming your pump is up to the task).
You certainly can spend more on a filter/regulator setup, but this is adequate for most setups in the 400hp range. Not sure what the top limit is. If you're going big (high hp or Nitrous) you might need something with higher flow capacity, but then you're probably also going to need aftermarket rails, bigger fuel lines, bigger pump(s), etc.

Sounds like something I will have to look into. I'm looking to be in the 460 range on motor and I'm going to push a 200 shot through it. I'm not sure if thats what I will need, or if I will have to go with an Aeromotive #13101. Thanks for the help guys.

The pre-2003 trucks (4.8, 5.3, and 6.0 engines) use a return-style fuel system. The 2001 5.3 I just built has this type of fuel system, but it fits the truk intake manifolds-don't know if it can be modified to fit the car intake. Hope this helps some.

Thanks in advance.
the next mini hurdle will be matching up line size and fitting. yours will be easy compared to mine.

Thanks y'all. I think I'm going to go that route first. If it can't do the job, then so be it. I appreciate all the help and the specifics! Keep your fingers crossed.
