Still not allowed to use my arm much because of the broken collar bone, I am doing small projects to keep busy.
I took a look at the Hart Tank Tender, 10 tanks, and other than being a little dirty, it all works. Tested it in some buckets of water. Works great. Didn't realize how expensive they are till I started looking up new tubing. Much was lost when the boat was deconstructed and I don't know what went into what tanks. So now I am looking for 1/8" nylon tubing. It works with simple air pressure, no electronics. But costs about $1,000. Now I just need tubing.
