adjustable fuel pressure regulator
The guy I purchased the car from says it has a TPIS adjustable fuel pressure regulator. I just need to know where its at...I think I found it. I'm pretty sure its right in front of the distributor,behind/under the intake? If it is, do I have to take the intake off to get at it? Thanks for the help, sorry if its in the wrong forum.

It is located in front of the distributor. It looks round with 6 torx screws holding it down. You will need a special torx driver to remove it since it has a little nipple in the center of the screw. To get access to it, you will have to remove the plenum.

If all you want to do is adjust the fuel pressure, there should be a nut in the middle of the regulator that you can turn with a box wrench. I have the Holley AFPR with the dial on it, so I don't have to use a wrench, so I'm not sure if getting a wrench in there is possible with the plenum on. Should be though.
