Where exactly is the fuel pressure regulator located?

 

Directly on the fuel rail on the right side. It has a vacuum hose on it going to the manifold. You would wanna test it by using a fuel pressure kit. I've heard a quick way to test it is to take the vac. hose off and if you see liquid gas in it then its bad.

It looks like this:

 

Ok I got it. Took off the vacuum hose and didn't see liquid gas. Thanks.
