For large fuel water separators, look for large diesel units. They have 1/2" or larger fittings.

Thanks gerry I purchased 2 of the larger ones from cp performance. They come with 3/4 fittings. Thanks for the invite but I doubt I'll be in the water by then. This has been one drawn out experience sucking the life right out of me. Its funny I've been reading different threads about new motors blowing up after a few minutes ( which i had 4 do last year), threads on how long it should take for motors to be built from scratch (anywhere from 4 weeks to 4 months, mine are going on 7 months), threads on procharger problems with set ups (boost pressure verses fuel pressure, boost reference, jetting, power valves, octane), . It all scares the hell out of me. I'm think I'm ready for a cruiser, this is the last try for go fast. I don't have the motor knowledge and I deffinity don't have the luck of finding anyone who really does around here. I'll give you a shout if and when I finally get in the water. Thanks for all your help.
