> The tank itself is not too hard to drop, but
it's hard to put it back up with all these vent hoses
staying connected.

Nahhh.  Don't try to connect them before raising the
tank.   Install your new lines or Y's or what ever,
but leave it handing from the bus frame.  Clean the
tank up real nice.  Reinstall the grommets in the
tank.  Put a little silicone on the inner part of the
grommets.  It'll help.  Raise the tank and put on the
brackets.  Don't forget the fuel gauge sender!!!
Then, only after it's in place, pop those five vent
lines back in place.  They go in easy.  Pulling out is
a bear, though.
