Fixed my tank no problem, after a few failed attempts.
Doesn't leak, weep, drip, smell, nothing.
It's been 4 years.
My wagon sat for decades with an empty tank, must have had moisture in it, bottom section had pinholes.
All are Tanksinc sending unit eliminating parts off of Summit.
Threaded C ring, bolts with o-rings, metal cap, gasket, not the cork gasket, the other one, neoprene iirc.
Left tank in car. Cut a hole where all the pinholes were big enough to slide the C ring in, drilled 5 holes for the bolts, done.
I had to bend one end of the metal plate slightly as it was close to the edge of the tank.
