I wrestled with the gas tank the other day. Not fun with 90% humidity, 90 degree heat...
There is a sequence...
(duh - hindsight is 20/20)
I always do things the hard way....
Stand the tank on its side, filler neck side pointing up.
Insert floor gasket onto the filler neck w/ vaseline
Then pop the grommet onto the tank.
put your rear hoses on the back of the tank now, give yourself plenty of extra lenght.
Lightly grease filler neck!
Insert filler neck through the trunk foor into the gas tank filler grommet.
Tilt gas tank into position.
Put on gas tank pad - YOu can use glue.
Pull straps up and throw on the J bolts.
Connect and pop a brew, you've earned it.
