Drain hose replacement is usually pretty straight forward repair. These are usually held onto pump end by some sort of screw or other clamp. Release clamp, take off hose , put on new, tighten clamp....
Am guessing any standard rubber washing machine hose will fit. These are sold at hardware stores, appliance shops, eBay, etc...
Once you have new hose fitted, can sort out pump issues.
Many of these vintage wringer washers were over built. Thus hopefully pump on your washer suffers from being laid up too long.
Once have sorted out hose situation, fill one tub about halfway with hot water, and let it sit for half hour or so, then try draining. This should help moisten any internal rubber parts that may have dried out from sitting used.
