Welcome aboard HI Replace the hose (hell, it's only 25 years old ) with new using the same spec on the old and one that also shows it's alcohol resistant. Most new, high quality fuel hose is these days and will be labeled as such along with the other specs. http://www.tridentmarine.com/stage/fuel.htmVERY cheap insurance.
The hose is definetly not 25 years old. It looks relatively new,
