Any suggestions for an inexpensive adjustable mechanical high pressure fuel regulator I could use to build a 150 shot stand-alone fuel system with? Most of the aftermarket bypass style regulators are $120-$150. There are bound to be some cheap OEM style regulators that would work for a 50 psi system. Any ideas?

You could get a L98 aftermarket regulator. The stock FP on the L98 is 42 PSI, so you should be able to tune the aftermarket regulator to ~50 PSI.Crane makes one for $67 (Jegs part # 270-99470-1 ) I just dont remember how hte are plumbed into the fuel system. Its been a long time since Ive played with those motors <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Also look up the Accel DFI regulator (Jegs # 310-74566 ) Its $97. Its made for a LT1.

As far as I know they dont have one for a LS1 yet <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Country Boy==Thanks for the ideas. I've since taken a look at the ones on Aeromotive's web site and I think I can make something from some of their parts. I'll have to have something that has a pipe thread inlet to use on the standalone system.

Hey Joe, are you running a nozzle setup into the throttle body or is it a DP system? If it's a nozzle, either single (NX) or dual (TNT) what kinda pump are you gonna run? I take it you would use a EFI inline pump feeding from a 1 gallon cell and then going thru a regulator before hitting the solenoid? I've been thinking about doing something like that. This way it won't stress the engines fuel system and take fuel away from the injectors. It's either this or go low pressure direct port, which I think works best. This way you can adjust the fuel in each cylinder. Especially in the ones that tend to run lean.

Toecutter--I was going to build a return type standalone system with its own pump and return with a mechanical regulator so that the nitrous system fuel solenoid wouldn't cause a dip in my returnless engine fuel system. I've put the standalone system on standby for now while I see if I can make the electronic fuel pressure control on my Mustang work better with a 100 shot.

If the fuel system is for a fogger, you do not need that high of pressure. I am using the MagnaFlow 300 pump running at 25 psi. The regulator is set to 19 psi which provides constant 19psi to the fuel solenoids at WOT. Foggers do not need pressure, they need volume <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

LS1290--Thanks for the note. It is for a NX wet kit on a Mustang. Single nozzle just ahead of the throttle body after the MAF. Fuel jet is sized for 45-50 psi when the fuel is taken directly from the stock rail. I could resize the jet for the lower pressure of a standalone system, I think, if it would atomize the fuel in that nozzle OK at the lower pressure. I haven't asked anyone about that yet.

The force of the nitrous does the atomizing of the fuel. 19 to 58 psi versions 900+ psi.
