Hummmmm.....sounds like you have a fuel managment problem, what are you using to control your fuel with?
O-rings sound like they are sealing good.

did you, uhm, maybe, to, i dunno, tune down for 740cc injectors vs stock 370cc injectors?

basically, if you went from 370cc to 740cc w/o modifying the powerfc, you're dumping in 2x the amount of fuel and running the risk of hydrolocking your engine.
