Joe,

Keep an eye on the neoprene. We had some issues last year using neoprene (I'm not sure it was Hayes brand). The neoprene was breaking down and spliting. My tank was a standard dubro, gas stopper, and brass tubing (no barbs). On my Yak, the neoprene split near the stopper. Also, my filter screen had black particles matted in it. I had to burn it out.

Itold a flying buddy using neoprene from the same batch to check his, and his inline filter (between the tank and carb) was full of the black particles. He had to replace the filter (couldn't get the stuff out). I'm pretty sure it wasn't Hayes... I'm thinking it was dubro neoprene Igot at the LHS.
