how to check for bad fuel regulator?

I think im having an issue with a leaking fuel pressure regulator....its off the car.....how can I check to see if its bad? or if it leaks?

Put a vacuum pump on the vacuum compensation port and see if it will hold a vacuum. Try holding it at about 20"Hg.

your gonna have to help me out here.....do you mean hook a vaccum up to the end where fuel goes in? and what do I do with the other end? plug it?

or the other way around?..put the vaccum up to the end the fuel comes out and plug where it goes in?

There should be a port on the regulator where a vacume line goes (will be a small bubber line that goes from the intake manifold to the fuel pressure regulator). That is where you should hook up the vacume tester.

I called Kirban Performance where I got the regulator and he was very helpful. He told me that all a reg is nothing but a spring and diaphram...and even if there was a hole in it and would not hold pressure the car would have a very hard time firing up if at all.......says he is 100% percent sure that my problem is my injectors but if for some reason it was the then he would replace it..

Glad to hear Kirban was helpful to you. What exactly is the problem you are having?
