I’m doing the same thing with a big blowtorch weed burning thingy.
I’ve lost the adjust knob (now use pliers)
The squeeze valve handle disappeared into the grass somewhere and the hose has been chewed on by squirrels(?)
I’ve bought hose, brass fittings, more hose, and a final hose.
The nozzle is just about rusted completely thru and I just realized I could have bought a new one for what I’ve been jacking around trying to keep this old one going.
Well, at LEAST I now have a 25’ hose insrtead of a 10’ one.
Well heck, Elsie. That thing should also be able to make a nice cup of Joe rather quickly!
