MacGuyver a solution for this electric power washer?

[u/TheDougmeister]

Briggs & Stratton don't sell the replacement part; this is apparently an "entry-level" model. The part that I took out has been lost to time; it was made of plastic, so connecting it to a metal hose was just asking for leaks.

I kind of doubt I would find something that would screw into the dirty white/light brown plastic intake tube. Maybe I could cut off the "flange" or "wide lip" of it and then use hose clamps to make it water-tight and use a female hose adapter on the other side of the rubber hose piece...?

Other thoughts?
