Hard to say. It doesn’t look like a super high pressure hose. Looks like 3/8 or 1/2 npt ends on it. Should be really easy to get replaced. I’m sure a trip to northern could get you back up and running. I’m betting they could build you a replacement hose there.
Had one go bad in my washer a couple years ago…. went to a hydraulic fitting place in town by us and they made one for me in like ten minutes. Just gave them the old one and they took over
The same hose with an npt cap on it will do the same. It can be longer than your original hose. I assume it’s being used to absorb shock from the water pump. Longer would absorb shock better. Your hose likely needs to be made of EPDM rubber. Not standard hydraulic hose.
Northern doesn’t make hoses?
Call Pirtek. That’s who we usually use at work. They’ll have everything but it’ll probably cost you $50.
