Duster 340 Pressure Hose?

If you have the old one, you could take it to a place that makes up (crimps) hoses and they could most likely replicate it. I have had hoses made up and driveshafts welded up and balanced at a trucking place I used to live near. Make a few calls and ask each for a recommendation if they don't do it and you will find a place in no time I'm pretty sure. They will need to see the old one though.
