Not sure what you're after...
There's three hoses to remove from the gas tank, the gas,
the vacuum one on the petcock and the vent at the back.
Sometimes people get frustrated with these, but they do come
off and go back on, really.

It's nice if the tank is mostly empty.
Don't set your tank down on its nose. It seemed to me like a good
way to keep pressure off the petcock, but there's a bunch of vent
passages and stuff in the tank, and fifteen minutes later a siphon
had got my tank to start squirting gas out the vent nipple.
There's about a million screws holding the top of the filter box on,
be sure to find them all before you start thinking the top is stuck.
Japanese "philips" screws are really not quite phillips, if you use
a phillips you might strip them out. The right thing is called "JIS".
I've had good luck with one of those el cheapo autoparts checkout-isle
screwdriver handles with a big tray of assorted bits... it has become my
"valkyrie screwdriver"...

Don't get frustrated trying to get the tank back on, if it doesn't drop right in,
study the petcock is having a fight with a lump of wires on the frame backbone
and figure out how to get it wiggled in...
