so actually I got the old hoses off the connector without doing any damage to it so I can now rebuild it. Question is what size male fitting fits into the female on the mobile maid power shower?
I believe thread is 3/8s of an inch. I have a new hose assembly on its way, too and I pretty sure that is what it was... I recently worked on a 59 Mobile Maid with the same problem, but the owner had kept a small section of the original hose and coupled it with a new one.
Hope this helps and please post some photos of your MobileMaid when you can!!
