My only suggestion is to forget about polishing the fuel--lots of trouble for dubious benefit. I would empty the tank and manually clean (or possibly replace) depending on the condition. The original tank on my 1995 model developed a leak on a trip to CRW that was likely a result of it sitting in some bilge water on one edge of it that eventually gave way and leaked the fuel into the bilge--definitely not a fun event. Since she is on the hard, now is the time to remove it (remove a few boards and it likely lifts out of the aft berth). With it out, you can take it to a local fabricator (one who builds custom grills, etc. ) and have them make a duplicate. That is the surest way to guarantee that all the new fittings end up where the old ones were plus they can add inspection ports, etc. I had mine made that way in aluminum for < 5 boat bucks and installed for another boat buck. Good luck with the upcoming 'splash'! Charlie NelsonWater Phantom1995 C&C 36 XL/kcb
