Was poking around under the hood today and noticed I have those blue top injectors, after running a few errands I popped the hood and noticed my fuel pressure was at about 22 psi. When I removed the vacuum hose from the regulator It jumped to 30psi. Is this the right fuel pressure? I was thinking it should be a bit higher. What would be the proper adjustment procedure. :hail: Thanks all..

NO...Per website, "static", vac hose removed, should be between 37-42pds. I hope you have an adj FP reg. All that is needed is to put a 5/64", I think, allen wrench in the top and turn clockwise to increase FP. That is really lean, hope you did not get on the car that hard. Also, once the car turns off the FP should hold for about an hour, if not you have other fuel system related problems. Thanks, Joseph.

Don't try to spin the allen headed adjustment unless you release the hex nut that holds it in place. And don't try any of this if you do not have an adjustable regulator.
