Fuel pressure regulator

[titogs95]

Well I am shopping for the Fuel system on my car!
I have the injectors 450cc and the fuel pump 255lph Next week I will buy the S-afc.
I will like to have a little help choosing some kind of FPR. The cheaper is the better.
I have a couple of options:
1-Aeromotive (I don’t know what model will be good for me, the simple and functional model)
I am thinking for the P/N 13101, P/N 13301, P/N 13105 or P/N 13109.<< this one is the common one.

2-Another option is to get the vortech. If, I do buy the Vortech. What model should I be looking for?

3- Is there another one that i can be looking for?

BTW:
Like I will be using an FPR anyway there is no need to use the stock one on the rail. So I am deciding to connect the 97 and up fuel rail with the return line hole. so I can connect the FPR easily after the fuel rail. And then the excess to the gas thank.

Fuel pump>>>filter>>>Fuel rail>>>FPR>>>Return line.

Or Should I keep with the Stock Fuel rail and connect it like this:

Fuel pump>>>filter>>>FPR>>>Fuel rail AND A return line from the FPR

Ohh well I bought I Vortech SFMU

and this setup is correct: (97-99 fuel rail)
Fuel pump -> filter -> rail -> regulator -> return line

for the 95 fuel rail you can do this.
Fuel pump -> filter -> rail -> regulator -> return line

the fuel line can be "t"ed off to go to the reg and to the fuel rail
but you have to disabled the stock FPR.

that is a really good page to check everything related to the fuel system on the 420A

the 95's already have a return line all you have to do is cut the return line and slap ur regulator in/on the return line. Easy as 1,2,3

this is a gasket setup for the 95 when you remove the stock FPR ur left with that big hole on the side of ur rail, slowboy has some kind of a gasket that just lets the gas flow into the fuel rail without the regulator there so the SFMU cant take over its job, really no need to replace your fuel rail, if you want to go for it though.
