There's a rubber block that fits on the tab at the front of the tank, the tab that locates under the frame, it fell off during removal and I can't for the life of me fathom out how the hell it fits back. I did it before but its got me stumped this time!

Anyone got a clue? Picture? Anything?

Ta

If from Tygas fitting guide but should be fairly similar :)
