Hi, have you tried setting up the pump on a spare channel (lets say Ch 6), assign Ch 6 to the throttle and set the pump (throttle) end points at what you think is 5% and 40% (something like -90% for 5% and -20% for 40%) you could also have it assigned to a switch either the ignition kill or a separate switch if you want to turn fuel off whilst engine is running.
