If the problem is a rusty tank, and I'm inclined to agree, then is the only
solution to buy a new tank?  This is a bummer since the PO had replaced the
tank with a new one not long before the transmission failed and he parked
it.

I read somewhere on the samba that some guy had drained the tank and
cleaned it with muriatic acid.  Anyone tried this?
