1995 Mustang GT Adjustable Fuel Pressure Regulator SMOG question

[rnowacki]

Not specific to a Saleen but hoping some others who like to mod their cars will have some input.

I have a 95 GT 5.0 with AFR165/24#/1.6 rockers/190#pump among other things.
Trying to pass SMOG in CA and all is fine other than the visual on my Adjustable Fuel Pressure Regulator.

I'm worried if I go back to a stock unit to pass SMOG the car will lean out. Are there any other options that are SMOG legal in CA?

Input much appreciated, and please no just move posts ;-)

Did you upgrade your adjustable fuel pressure regulator to another brand? Do you have the 4 stock cats or x-pipe with 2 high flow cats?

Jason, which Aeromotive adjustable fuel pressure regulator has your shop used on the 1994-1998 S351's?

I went back to the stock fuel pressure reg. Measured the pressure before and after the change and it was exactly the same. Basically the aftermarket adjustable wasn't doing anything the stock unit wasn't. And I finally passed SMOG!

I had to switch to the magnaflow 4 cat CARB legal unit. I still have my bassani x with 2 cats sitting in the garage.

I dont have much experiance on the 351's, but my tech has tons. On my 02 we used the Aeromotive 13101. I would imagine it really depends on your power level and what size inlets and outlets for the hose size your going to need.

A1000 Injected Bypass EFI
Regulator, Adjustable, (2) -10

inlets, -6 return

Sweaty palms/crossing your fingers hoping you'd pass i'm sure. Glad everything turned out well.
