I had an identical thing happen to me. A new cap was not the answer. A new fitting was the answer. The cap and fitting are both aluminum, which doesn't seem to like sewer gasses all that much. Since I was tossing the fitting, I think I just unscrewed it from the deck and slipped/pryed the hose off and removed it. Stuff a rag in the open end of the hose so you don't pass out. Then you get to fill the mounting holes with epoxy and do that deck penetration correctly.

Even with a good spanner wrench I could not budge it. I sprayed PB Blaster on it. If the O ring is good, the Blaster may not penetrate. I thought of drilling holes, inserting bolts and using a breaker bar and buying a new cap. Other less drastic ideas? -- Joel 301 541 8551 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
