Right now I've got a hose in aloop on back of engine,,cause I haven't commitedyet to buyin oEM hoses.
My long term concern is fixing it/ preventative maintenance on something really old.
This thing is pretty unique and getting something similar and cutting and soldering my be the way to go.
The other possability is to grind/de- solder the joint to the bracket,,pull valve guts out , solder a cap on pipe , weld/ solder it back to bracket.
Then put a valv in the hosethat yo operat 2 time / year.
