BEGI owners
Thought I'd pass this along to fellow BEGI owners. I'll post on the Twin Screw thread as well...
Bill (koenig928) and I were finishing a Shark Tuner session when I noticed my fuel pressure gauge was pegged at 99 psi at idle! I immediately turned off the engine; luckily we were at a turn off an no traffic. I popped the hood and didn't see any problems, and then we checked the fuel pump fuse and relay, both good. I started the engine and had normal pressure. We logged another WOT run and went back to Bills to burn an EPROM.
She ran fine for the first 8 miles then the fuel pressure pegged at idle again, I'm assuming it was in the 100's because my gauge only reads to 99. Only this time I was in a bad location on one of our busy highways and no shoulder to pull off on. I couldn't start the engine because the pressure stayed maxed. I started checking the basics as before and the then removed the fuel pump relay and jumpered the connections, still pegged 99 psi. Then I tried to by-pass the BEGI by removing and capping the vacuum lines, it still didn't change the fp. Had to call a flatbed to carry her home
As soon as we got her parked in the garage, I checked one last time and it was still bad. So I decided to go after the easiest thing first, I took the BEGI apart and sure as **** the aluminum square was cracked which allowed a constant vacuum leak? Luckily I had several spares on hand that Mr. Corky Bell himself sent me several months back during trouble-shooting inconsistent fp's. I replaced the aluminum, put it back together, and she fired right up
I can't believe how the BEGI is put together; in theory it's a big component for such an easy design. I'll be very happy to get rid of it and not have to worry if it's actually regulating my fp's correctly

It's an after market Fuel Pressure Regulator designed to operate off vacuum.
Here's a pic Tony took a while back. It's the one that looks like a Flying Saucer

Do you still need all those gadgets after ST'ing?
