I installed two switches, one for each fuel pump, and turned them off first. Still had the fuel drip. Since my intakes run downhill, and the TWM throttlebody is also pointed downward at a 45 degree angle, apparantly the fuel coating the insides of the long intake tubes slowly runs downhill toward the throttlebody, and eventually leaks past the butterfly. I'm considering installing the short intake I have from Atkins Rotary. It puts the injectors back on the hot side of the engine, but should eliminate all that downhill plumbing I have. Thanks for your input. What kind of static rpm's are you getting on your takeoff roll ? Thanks again.
