russ, btw, i put the trucker style pull wire on my 3 main big tanks.
the wire pull i drilled a hole in the back bay back wall and the same in the front bay. the pulls are in the bays and i just open the bay and tug on the cord till they bleed off and let go. very easy and fast. it is the same thing truckers use.
they are ten to twelve dollars apiece. they are all 1/4" npt. take out the current drain valve, screw these in (and they have a pivot that the cable attaches to) and route the cable.
