I have a reasonably important question, has FloScan upped the amount of fuel they will flow at WOT??? I admit it has been a few years since I installed these on several of my clients boat, we had two V6 OB's burn pistons. We suspected the FloScans and installed vacuum gauges on two other boats and found the FC's restricted flow well above the allowable vacuum margins. I do think they are a great unit but far better suited to those that cruise! But am more then glad to be corrected!
