Ok here is what i've got, i'm going to be boosting my 95 auto ESI and i had some questions on the fuel system. I plan on using a walbro 255 lph in-tank fuel pump along with a 12:1 vortech FMU and the stock injectors for now. I plan on boosting around 6 or 7 psi. My questions are in regards to hooking up the FMU, my fuel system has the regulator on the fuel rail but i don't know where the return line is, the regulator only appears to have a vaccum line coming out of it. Can someone tell me where the return line is on a 95?(if anyone has pics of an FMU on a 95 that'd be great) Thanks for any help you guys can give

So that is the return line then, I thought it might have been a feed line when i first looked at it. So basically all i really need to do is hook the fmu up between the rail and the hard line on the fire wall? That makes thins so much easier. Thanks

Please read the other two links in my post. That's not all there is to it, you need to modify the stock FPR as well.

Those post are for adding an adjustible regulator and they're doing the mod on the stock regualtor to adjust idle pressure. I'm only putting in a rising rate regulator, this doesn't affect my idle pressure right? Mind you i'm still running the stock injectors. Do i need a seperate fuel pressure regulator along with the rising rate regulator?

You're right, sorry. You only need to disable the factory FPR if you want to lower your fuel pressure below stock levels.

I'm guessing you have a basic Star kit so disabling the FPR isn't neccessary unless you get larger injectors and an adjustable FPR like an SFMU.
