Removing

O/s/r wheel
lay on the floor and look up where the pipes go
On my image i have already removed the filler flap, but you can clearly see where the 2 holes where it goes
My advice
Dont snap the bolts
Work the nuts, loosen, tighten it up - loosen it a tiny bit further, to work it loose
I've had todo this with both of mine
They will be dirty - a spray with cleaner / penetrating oil does help
Dont undo one completly while your working the nuts free/clean the threads, it'll make the flap smack around
