Good it worked out.
This may be the reason for your other Post about ‘gas fumes’. An overfill or spillage occurred and what you smelled was a splash of gasoline slowly evaporating from the fender well. It’s a good idea to check the filler neck connection hose too, they can also deteriorate too.

The washer hoses is just tedious endeavor very tough to remove the hose from the nozzles, don’t try to remove nozzles, it’s not necessary. But use a hair dryer or very low heat to warm up the hoses and they’ll slip off easier. A mirror and cellphone cam help seeing under the cowl. Oh - mark those hoses before taking them off, remove and replace only one at a time. I added an extra 6” length of hose from the nozzle to the new check valves and T so it will be easier to remove after another 40 years.
