thanks kev. the tank is in the rear corner, with a small piece of casting deck above but otherwise in the open (its an open tinny)
i'll definately look into a remove filler neck- what do you mean mounted properly in a cradle?
the reason it's a little difficult to remove is because there is a strut welded on (not even entirely sure what it's there for) which makes it a tight fit (22.5L tank)
nowhere else i can really put the fuel tank in my setup
cheers
Dan
