How do i check or test my fuel pressure regulator?

[tundra2000]

I couple days ago i had a problem with my fuel pressure regulator spraying fuel out the return line part before i could even get the car started so i pulled it off today and would like to know how i can test it or check it, I tried using the air tank at about 42psi and spray the air through the part that the fuel goes through then out the return line and i didn't hear any air leaking, i don't think thats a good way to test it but i'm trying to figure this out so i don't have to buy a new one.
its on a 1995 talon with a 1g in it turbo.

Its a larger fuel pump that can potentially overun a stock fpr, especially if its old. You can go to most car part stores and buy/rent a fp tester with a gauge on it verifying what its holding your fuel pressure to. Just be sure when your doing the test you follow the Mitsu service manual procedures...
