Took off the trimmer head,pulled out the broken piece, removed 2 bolts and removed curved shaft and with pliers removed other piece bof drive shaft. Then with hammer and punch started to move flexible liner. As soon as enough liner is exposed, pull liner out with pliers. Installation is just the opposite of removal.

I had a grommet, inserted fuel lines through holes in grommet inserted it in fuel tank that took care of gas leak. Replacing shaft and liner was straight forward, took bolts out of motor housing, pulled shaft tube from motor housing and removed bolts securing head to shaft tube, took string head off. I was than able to pull old shaft and shaft liner from tube and install new parts.
