I purchased a 1982 45' Lancer Masthead Sloop in June of 2020, I spent the last few months renovating and upgrading just about everything. I have been having issues with fuel and losing prime when hitting rougher water. Anything rougher than the harbor. Found a lot of junk in the tank during a fuel polishing. There is not very good access to the tank to do a good cleaning. I am thinking of taking the floor up just over the tank and cutting access holes to access the interior of the tank and try to do a betting cleaning. I have also thought of replacing the tank. I am wondering if anyone has experienced this with this boat and if so do you know what issues I might run into trying to replace the tank.
