This is the coupler I am talking about
BTW - Thanks for the write up. I've got everything set up except for this last piece that I am hoping doesn't need to be machined out.
@ExpressDetail - Question about the M-22 X M-22 coupler used from the hose on the pressure washer to the new quick connect. The female end inside the pressure washer side is too large to slip inside any of the couplers I've tried. Did you have to drill out the inside of the coupler to get it...
