Chris,

I just went through the same thing myself.  Had the tank on my 81 out three
times before I realized that is wasn't the grommets or hoses (actually it
was at first) but a leaky, corroded tank.  Took it to a local radiator shop
and they coated the inside with something that stopped the leaking.  Cost
$80 but cheaper than a new tank.

The first time I took the tank out it took me two days but by the forth time
I could take it out and put it back in in under two hours.

Good luck

PS: If  I could just get the oil and transmission fluid leaks stopped the
easy I would be happy.
