Fuel Pressure Regulator

[PTcruzer02]

i am interested in adding an aftermarket one. but they say something about having a return fuel line. and from what i have read gt's and srt4's dont have one. so is it still possible to hook up an adjustable fuel pressure regulator?

You can run a schrader valve off the 03 fuel rail to an aeromotive fuel pressure regulator and run your own return line to the tank... Total cost $350ish. Make sure you run boost regulated pressure as to not starve the engine... That is hook the fpr to any boost line so when boost increases so does fuel pressure. If it sits at a static value and the demand increases new motor go boom.

i will be running a fuel pressure gauge and a air/fuel ratio gauge if any problems were to arise. now is it hard to run a return fuel line? you did mention a brand(aeromotive) but which one of there's would i go with? I'm only running a fpr because I'm using my stock 02 computer because the changed computers in 03. so I'm think this would be a better alternative then to by the Hahn porter fueler system (1,200).

the computer is a long story but i'll make it short. i have an 03 gt computer but the plug ins are different on my 02 limited. it seems chrysler switched in 03. my computer has two large plug ins on the side where as on 03's and up they have 4 small plug ins that come from the front. i'm fine with running the stock computer its just that i need to make sure when i boost i'm getting enough fuel.

You can get a safc II for $150 used on the srtforums. That will control your fuel based on rpm instead of throttle position (much safer). You will also need bigger injectors, i am selling my S1 injectors for $50 shipped

Just read your sig... Nevermind on the injectors

[PTcruzer02]

i'm familiar with the apexi managment systems, as in i know of them. is the initial install easy on these and also the settings are they easy to figure out. i don't mind buying it brand new but the safc II's are discontinued its now afc-neo.

[ChefTank]

Settings are super easy if you have a wideband to monitor. Install is just wiring, if you have too i called a local shop and they said $80 to install... I'm sure you can find the same near you.

in that case this is great and has been very informational. i may pm you in months to come to see what settings you had. i didn't know shops actually did all this. i was just unsure because you you cutting pcm hours made me uneasy. but i will be taking you advice instead of spending 1200 i will only spend about 600 for apexi afc neo and wide-band air/fuel ration gauge.
