Today after gassing up my car...my car sounded funny...so i pulled over and listened for the sound...it was coming from the rear of my car so i figured it was my fuel pump...so i just drove it home..when i get home i see that my fuel pressure gauge reads past 100 pegged onto that little stick...is the gauge busted or my fuel pump busted...or the regulator?!?

 

What kind of FPR do you have? The cheaper versions have a weaker mechanism in which will have a tendency to foul up. A buddy of mine had one and the inner spring broken, allowing too much pressure to pass by. Did your "check engine" light come on? It will if you are actually feeding the motor too much fuel.
