Back to the boat- Fuel tank

[fetoma]

OK guys, I had a project to get done and now I'm back to the '86 V20 I bought earlier this year. My boy has been bugging me. So I took the cover off the fuel tank. Doesn't look too horrible I'm guessing. The tag states it's a Patriot 49 gallon. My plan was to pull the sending unit out, drain the fuel, and inspect the inside. One thing I know it needs is a new line from the tank to the motor.

Any other input or thoughts from you guys would be great.

Thanks,
Frank
