i would still raise the issue up before the manufacturer. if nothing else it will give there technical department another instance of a possible malfunction to add to there data pool.

this nitro fuel is dangerous, but thank God that was not gas. I had a gas can go off in my hand one day. i avoided a trip to the emergency room because i had a nomex blanket (dad was a diesel mechanic.....i sitll have that) over the arm i was pooring it with(i was dumping it on a fire.......i stopped after that!!!!). that sucker went so fast it blew me off my feet, and im a big old boy(at that point i would have been 5'11 to 6'0 and about 250....). i think im fixing to attach a potentiometer somewere inline to regulate the fuel flow on my pump down. i keep shooting myself by accident
