Re: I28 - Gas Tank Info
Sunday, I don't know what was built in, but after 40 years it could be time to pull the tank and clean it out. Refit as needed while it is out.
It is a bit of a PITA but the fuel tank can come out through the portside lazarette. Typically you'll need to disconnect cables and wiring that may block it from moving across and it will be a tight fit, but the hour or two it takes to clear it out (and back in) is a good trade against how much easier it makes work. If there's no inspection port, you'll have to pull it to add one anyhow. And of course cleaning it out is much easier when you can turn the tank over and dump the crud out.
