Hello all, I put on "x" shaped o-rings from McMaster Carr, and lubricated them with teflon grease similar to the Super Lube just mentioned, which I highly recommend. In our case, it is teflon grease sold by local pool stores for lubricating pool equipment o-rings. I believe it is also food grade.
The x-shaped o-rings stopped all the leaking from the caps entirely. The orings I ordered are: https://www.mcmaster.com/nav/enter.asp?partnum=90025K412, though I would recommend going one size larger, as they were very tight going around the threads of the caps.

Disappointing news about Kracor. Typical unfortunately of what happens when a small company is taken over by a large corporation. I have observed that the flat tops on the fairly thin roto-moulded tanks bulge quite a bit when full, and I have not been successful in stopping the clean-outs from leaking either. Like you, I have reached the conclusion that this is just a design "feature". I thought about lubricating the O rings, but couldn't think of anything that I wanted to have in contact with drinking water.

South Shore Yachts was able to quote new tanks from a third party but at over $1000 each, plus shipping to Florida, seemed cost prohibitive. Ultimately, I used a Florida tank manufacturer & repair facility, Seelye Inc., in Ocoee, FL to repair the crack in the tank. The cost to weld an 8-inch crack was $65. They tested it to be leak free but there is no warranty. On reassembly, I had trouble getting a seal around the suction fittings, which are Qest elbows, but found that if I first connected the tubing to the fitting and then screwed it in, I could get another couple of turns on the fitting. Both tanks are essentially leak-free except for a little weeping around the inspection ports if overfilled. I plan to avoid overfilling. While at it I also replaced the 4" o-rings on the tank ports (AS568-240), and on the old-style Jabsco suction strainers (AS568-131) and installed a Teflon back-up ring (AS568-007) under the strainer cover screw heads. Now on to the next adventure... -- Tim Rutherford Chamamé C&C 36' - #244 _______________________________________________ Thanks everyone for supporting this list with your contributions.
