So last year I had one valve section, three from the end sticking, I carefully unstacked the sections, fixed that one and tossed in a couple new o-rings. now further up the line, there's a minor leak between the sections so I'm thinking old o-rings plus disturbing them equals ooze. There is only one part number listed, 24321-000650. The valve block is beneath the floor and looks to be a treat to remove and reinstall, lots of hoses in a tight space. The oring groove in the block valves is well defined, I'm wondering if it'd be possible, after draining the tank and cleaning everything up, take the nuts of the outboard side, then carefully pry apart the first secton, put in a new o-ring and work toward the last. Imagine the typical procedure is to remove all the pilot and function lines. get the block on a bench and reseal it before putting it back in place. Any good pro-tips welcome.

Be sure you mark the hoses with colored zip ties
