I had problems with fuel delivery on my FITECH EFI system. After being pulled back to the pavilion 3 times by Alan Stark (Thank Goodness for him), I'm running their EFI system with the Command Center, (remote sump tank fed by my mechanical pump) Runs fine on the street, but basically first trip out on the trails ran great for about 30 minutes and acted like my fuel pump died or ran out of fuel, got towed in, got it back running, and basically the same thing happened, actually burned up the high pressure fuel pump, replaced that, then still acted like it was running out of fuel on the trail, no fuel coming from stock mechanical pump, so I replaced that. Still died on trail, Ran great all over town. FITECH Support was great, even got to talk to the Designer of the Command Center. So after replacing one high pressure pump, one low pressure pump and talking to FITECH support, Ken, who designed the Command Center suggested that I disable the ROLLOVER Check Valve in the Command Center, that fixed it. So the problem was the machining tolerances were so tight that when pressure built up in the Command Center the vapors were pushing the check ball closed, causing all the problems. They had already had that problem and made a design change. They are replacing my fuel pump and the Command Center under warranty. So its all good, gave them some free R&D I guess. After disabling that check valve the system ran flawlessly on all types of terrain.
Man, I know you were aggravated but glad to hear you got it worked out. It's all part of wheeling I guess. Hope to see you following us next year.
