I've got the old version of this lead (O101) and it works a treat.
For future reference, if you need to access the battery, etc. again, you might find it easier to just 'hinge' the tank up and prop it with some wood, (or I use offcut nylon plumbing pipe) like this...
If you twist it, as you've done in your picture, you might disturb the fuel connectors, which are not particularly robust.
