Problem fixed
Worked perfect. No more air leak so flushes at peak power again. Make sure to cut the hose as close to the old barb as possible like directions say because there is not enough hose to mess it up. If you do then you will be taking the whole Flushmate system apart to put another hose on. Not hard to do, but a lot more work.

Its a direct fit
This is a direct fit for sloan pressure vessel. Suggest removing the hose from valve, rather than cutting it. Had to use a little bit of teflon tape on threads because it leaked from threads. Thats why this gets 4 stars. Try without first the teflon tape first to determine if you have a leak
