Lifting fuel tank

[ade the blade]

ok....this might sound a bit silly.....have you disconnected the two breather tubes on the bottom of the tank ?
once you have removed the front bolt just slacken the rear one to allow it to move,lift the tank to about 20/30 degrees and this will give you enough room to release the breather tubes you can then lift the tank a bit more and then disconnect the wireing for the petrol gauge,tank should go to 90 degrees but as already said not when the tank is full 

last time i lifted the tank 20-30 degrees and slid my hand under, a baby conger took 2 of me fingers clean off !! :rolleyes
