I have not gotten around to testing them, other than grabbing the top one on the pile and plugging it in. It worked.
I did not check model numbers, so if you need a part, could you email me a picture of what you need? Then I would know what I'm looking for. Might have something similar. The 2 boxes have parts.
I suspect the hoses may not be airtight, and may be pieced together, so they would not be reliable or original.
