Ion XE leak
My XE has air leaking around the noid fitting closest to the tail of the gun (not a typical banjo, its gold, not sure what it's called but not the same as in a regular Ion and I don't have an XE manual). The fitting has a green seal, not sure it's an oring, it's flat on one side (this may be the problem - worn ring). Anyway, is this normal, or do I have a problem? Anybody know where I can get another green seal ring? Thanks in advance for your help to an Ion noob.
