On the left side of the tank there are three hoses grouped together that connect through a small filter piece. Does it matter which of the three hoses attach to which of the 3 ports on the tank. Are they interchangeable?They seem to be to me-I can't seem to locate the answer in my manual.

It does not appear that it makes any difference. This is a liquid/vapor separator device. I believe you are talking about part #5 on the lower part of the diagram?

Yes Thanks so much
