I know there are concerns about ethan-crap causing issues especially in the marine business. I had my pump done by Tand N and it works ok. They returned the old valves so that is always a fall back position and the valves are pretty bulletproof. The two variables are the real issues I think... the diaphram and the valves. I don't know what George's isssue was with them but it seems to be ok in Stinky.... knock on wood.
