My 20-REVENGE is from approximately the same era. Replacing the fuel lines from tank to filter to outboard was a simple project. There is good access to the path and the hose is not very expensive.As LHG mentions, it may be that the rubber lines in your boat are not the type rated to resist alcohol-laden gasoline.
The addition of alcohol to gasoline is very common in the midwest. It makes no scientific sense but contributes millions of dollars profit to the Archer Daniels Midland (ADM) company and to some midwest farmers who have grown more corn than market can buy.
ADM is extremely active politically. They paid for Bob Dole's kids to go to college. They sponsor many of the Sunday morning political shows. They were fined over $100-million--the largest fine in history at the time--for fixing the price of farm comodities on a global scale with overseas producers. In short, they are the worst kind of company, and they are the ones that used their political friends to whom they taught cocktail-party science to get alcohol added to the gasoline under the banner of ecology.
As a result, any rubber hose in older boats and motors is now subject to hardening and leaking as the alcohol in the gasoline affects the hose.
