adjustable fuel pressure regulator
Has any body installed a pressure guage on the end of the fuel rail? What did you do, will it drill and tap directly? I have this adjustable fuel pressure regulator, see pic. Will this work and where should I put it? Or does any body have any other suggestions instead of this for boost. Like a rising rate FMU? Not sure what I need to control fuel to my novi 1000. Ive got the 8.1 injectors and inline 225 LPH fuel pump but am not sure how to increase the fuel along with the boost so I don't lean out.

I have hp tuners but i just finished the heads and am now in the process of getting the engine running then i'll hook up the charger. I just wanted to get all info and parts now. I know that I can adjust the stock pressure regulator but am not sure how much. I want the pressure to go up with the boost so I don't lean it out under WOT.

You can go to an aftermarket FPR. Not sure what it would take for a Radix, or if it even worth the cost/effort. Most of your better ones out there have a boost reference port. I have a Fuel Lab FPR that is going on very soon when I switch to a FAST intake that has that option.

tweeder, are you talking about your truck in your sig? A 2000? You should have a return fuel system. You should already have a boost referenced FPR on your rail. More than enough to take care of your set up. No need to screw with it, adjust. Just hit boost and it will take care of the rest. Especially with the 255 on there.

Don't worry about the FPR until you need to change fuel rails imo.

Thats good news that I don't have to spend more money. Lord Aries ebay is your best bet, I see alot of buy it nows for $80, but you can get one cheeper. As for not needing a FMU, how come some of the kits come with them?

$80 Thats it??? That dirt cheap (compared to what I am speading on the rest of the motor LoL)! Damn, if it will help me to have better AFR (and MPG) when not under boost i will be putting one of those on for sure... Is there one kin din particular to use?
