id say 55 psi is a good starting point for you...if you have the stock regulator in the tank still than thats gonna be pretty much your max fuel pressure.

i realize your using an adjustable FPR but that still wont help you push past 55 psi. As long as the stock regulator is in the sending unit, it will not allow you to increase pressure past that point. If you remove the regulator then it wont even pump. You need to get a ball bearing that will fit in place of the stock regulator this way you can gain full control over pressure and adjust it to whatever you want through the aeromotive

what do you mean ball bearing? what the hell, why do you not have to do this on any other car. Im aware you gotta remove the stock FPR, but i got a adjustable aeromtive FPR, that should be all I need.

yea, like I said, you need to fit something in place of the stock regulator or else I promise you it will not pump with nothing in that spot(I know from experience Im not making it up). Talk to someone with a Sound performance kit, I can almost guarantee that since they use a return line that they pulled the in tank FPR and plugged it up with something else. If im not mistaken I think there was someone in the FL area that is running a return line setup like that(maybe that guy Rasta?)

U can't use a fuel regulator if you don't have a return fuel line. The ECU controls the pressure depending on the situation.

there are fuel pressure regulators i have seen on ebay if im not mistaken, simplyscion is right, just like with an intake, no matter how big your intake piping is if your throttle body is not big enough to match it, it wont take anymore air into it

you need to block the stock regulator. I have never seen a tc regulator but on srt4s i've used a thick washer pressed into the regulator.
Then you can control the fuel with the return line.

no my theory is fine. I know we dont have a return line setup.
In another post he is asking about a return line setup.
Also in this post he is talking about a return line setup.

He wants to install one. This is how it will work.

Yes we do have a return line, there are two lines for fuel in our cars, one for the supply and one for return, check it out if you dont believe me, there are 4 lines going to the back, 2 for rear brakes, and 2 for fuel, i mean i know we dont have two supply lines, so one of the two has to be return

its a returnless fuel setup made for emissions purposes. Even my Acura is setup with a returnless fuel setup and Honda's are notorious for having return lines. Most modern cars today are returnless due to strict emissions.
