I replaced my faulty fuel pump. The new pump is MUCH more quite. I suspect the old one was on the way to failure for a while and finally when belly up. It was really noisy. When I took it off I applied power to both independently and the
old one was just plain dead.
I hope I have addressed the few gremlins that has kept me on the ground the last few weeks and will get to fly later today.
FWIW.
