So the other day my brake booster took a dump on me, while replacing it in the parking lot, I noticed that there was a fair amount of gasoline in the old one. I am pretty sure there is not supposed to be gas in the brake booster. After a bit of research online, it looks as though I may have a faulty Fuel Pressure Regulator. My question is, is there a simple way to test the FPR without buying some crazy tool? I pulled the vacuum line of of the side of the FPR that points towards the firewall, the engine doesn't seem to respond to that but i noticed that there is fuel in that vacuum line. Is that normal? Any help would be most appreciated!

I don't have any Bronco experience (I try to stay away) but I'll confidently say that the FPR is definitely faulty if you are getting gas out of the pressure port.

Here's some Ford-specific evidence to back that up:
