Waste Tank Replacement
I just completed replace the waste holding tank on my '92-30T. It's not an easy task. There are conceled fasteners on the starboard side, the same as what is on the port side. As you said, they are in accessable. I opted to cut my tank out using a mini grinder with metal cutting blades. The replacement tank I used was a Ronco B131 15 gal. tank. It's just about the same size as the old tank. The new tank went in surprisingly easy. A note of CAUTION. Be careful when you are cutting along the back side of the tank.[starboard side]. Your throttle and transmission cables are routed there. Don't make the mistake I did and cut the cables, although after 16 ears, they did need to be replaced. I have instructions that were send to me by another owner with step by step proceedures to replace the tank. I can email them to you if you wish.
