Adjustable FPR for 4.0 OHV

SVO · 11-21-2003, 01:20 PM

Does anyone know of or has an adj. fuel pressure regulator for the OHV?

I sure could use one.

Nope.
Not a bolt on one anyways.

Now some of the fuel management systems for the supercharger kits may be able to be adapted, but there would be more to it that just bolting in an aftermarket adjustable unit.

You can also fabricate one to work, one from a 5.0L possibly.

Pat Kunz JB welded a buick regulator to the 2.9L fuel rail years ago, worked well on his truck....

On the SC applications you must be talking about the FMU's.

And I would like to see pics of the Buick mod.

Why do you need one?

I had a FMU on Splat. Basically went between the stock FPR and the return line.

Tuning purposes.

You can only trim out so much fuel with the programming before you have to do it mechanically.

The buick regulator won't work on a 4.0 because the adjusting screw would point straight down and wouldn't be accessable.

You can use the Cartech #2025 or #2027 which is an FPR/FMU but if used with a standard n/a engine just a FPR. There again why? If you need more fuel step up to 24 lbs injectors and then lean it out with your chip programming if thats your problem. Also, unless your running alot of mods on your 4.0, more then the standard bolt ons, I see no need for such.

Later Doug904.
