Just a quick little update. I got the car out today and put a few miles on it. I had about 3/4 of a tank and did anywhere from mild to 3/4 throttle acceleration.(took it easy breaking in the new clutch) The fuel pressure stayed costant at 5.5-6psi, no leaks, and all seems fine on the install. Hopefully I will get it out again soon and drive it low on fuel to see how it really does.

Quick update: Got the car out again yesterday and today. Ran it until under a quarter tank. No problems on normal driving. Got to about an 1/8 tank and decided the new clutch had enough break-in and tried a couple hole shots. Left at 3k and ran through the gears. No problem the first time, so I tried again. Same thing, fuel pressure stayed constant between 5.5-6psi. Looks like it's working so far.  :D
