A while back someone posted something about vacuum system leaks. My
system works well except that I have been unable to find a reliable
check valve. I have tried three or four different check valves, and on
all of them, if you put a hose clamp on it seems to distort the case
and not check properly but if you just push the hose on it isn't tight
enough and it leaks. What check valves have other people found to
work? thanks
