differences between normal 4.0 and high output 4.0

I wouldn't consider that a huge downside. Sucks when it does happen, but it doesn't hurt anything. Chrysler has a sleeve you put on the fuel line to help prevent this problem.

That is the TSB "fix", seems that preponderance of users that have tried it had NO IMPROVEMENT. Poor old Muddeprived has a couple EPIC threads on his problems, with the fixes attempted: dealer injector condom, extra aftermarket heat shielding, hood vents. I believe his problem was fixed by adding a timer circuit to the aux fan so that it runs for a couple minutes after shutdown of the engine.

not to be nit-picky, but it's actually the other way around. the line at the regulator is the return, and the line closest to the firewall is the feed.

Ill agree.

Renix had the pressure line enter at the front of the rail, and return was at the rear of the rail.

Meh, close enough. We don't get enough Renix rigs in work to pay attention to.
