What adjustable fuel regulator will bolt in?
Does anyone know of a adjustable fuel regulator that is a bolt in replacement for the stock one on our cars. I have a 97 sc400.

As far as I know there are no direct replacements. OUrs are in the tanks and I havent seen one that will just drop in the tank and attach to the fuel pump besides the stock one.

Easy??????
Well I guess that is a relative term
I did mine by myself it came out pretty good so yes it is doable but I wouldnt call it easy. I installed an aeromotive. I might do it a little different if I were to do it again but you can see what I did here.

Aeromotive. I had one on my SC400. I forgot the Model #. If you call them they can tell you. It replaces the stock FPR on the Pass side fuel rail.
You need that 90 degree bend in the pic to make it work and lay down, otherwise you can't close the hood. At least I could'nt.

jgscott,
I have the aeromotive Part, I am trying to make sense of the diagram you provided. The small regulator on the fuel rail, Do you gut it or just use it as is? For some reason i thought you would delete it. I am trying to plumb this in and just want to make 100% sure its right.
Also do you happen to know the stock fuel pressure for a SC400?

You should went with SX Performance EFI regulator and filter.
Aeromotive would work too.
What is the Aeromotive regulator P/N?
It should be same regualtor set up for my Z32TT.
After plumbing (conencting in series per JgScott's picture), you have to set the base pressure with the adjsutment screw (fuel injected motors are usually 45 psi) but check for your SC).
And then, you have connect the supercharger boost hose (vaccum line) to the boost reference port in the regulator (red hose) so you can raise the fuel pressure when you boost.
You might want to get the fuel filter (Blue cylinder) for an insurance.

Scott, I am pretty sure you can set it at 43 psi and be dead on. Keep in mind that you want to set the base pressure to 43 psi while the car is idling and with the boost/vacume line hooked up to the regulator.
If you set the pressure without the boost/vacume line, when you hook it up the car will be running under vacume and prssure will drop to qiute a bit less than 43.

Scott, extend the fuel lines & mount the regulator else where.
Either on the side of the engine or on firewall, like in the pic.
MVP sells a trick engine mounting bracket for the 2J you could
modify.
OE pressure? Most people run 43psi static. (engine running/ idle,
reference vacuum line plugged) Start there & increase if your lean.
