    Yes, I have done it lots, usually because I forget something when putting it back : unamused:

    What would you like to know?

    I am not particularly technically minded but I managed it without any real issue or concerns.

    Take some photos of which fuel line goes where. Red top? Or red bottom etc...I never remember, but don't need to as I have a photo.

    Do you have a manual? They break the steps down...but it's straight forwards enough.

    Make sure the bike is supported and safe.

    Take off the seat
    Take off the side fairings
    Undo the two bolts holding the tank - one by the headset. One by the saddle front.
    Lose the bits and look for them later (like me), or put them carefully to one side noting the order of any nuts and washers etc.

    You may be able to access the red and white fuel lines which need to have the sliders squeezed to allow you to gently pull off (outwards) each connector. If you can't get podgy fingers in there - see below.
    You should be able to ease the tank up and slightly back...kinda pivoting on its rear. Try not to scratch it on anything as you do.
    Try not to overstretch the fuel lines of still connected. There's a bit of give in then but not much.

    There will be a couple of electrical connections on the tank - I think one on the base and one on the side - which, if you're used to all this you'll unclip easily with one hand as you support the tank with the other.

    Or, if you're like me you'll dick around for half an hour wondering how they can land a man on the moon but you can't undo a simple plastic connector. And you'll shock yourself just how pissed off you can get about something so seemingly simple. Until you suddenly get it and you'll wonder why o why you found it so difficult as actually it was easy. And you'll remember that next time (except you'll forget).

    If you couldn't get the fuel lines disconnected before you should be able to more easily get to them now...maybe get married and when things cool off with all the passion side of things and you get a bike, you can then at least then ask your wife to hold the tank whilst you fiddle.

    Or you can use a rubber mallet or something to prop the tank up on the handlebars or air filter, freeing up another hand.

    The rubber mallet can save you a fortune in wedding costs and, frankly renders marriage virtually unnecessary.

    There are likely two little rubber hoses coming out the side/ lower side of the tank from a couple of nipples. They run down the side of the engine towards the ground. Take these off, or pull them through the frame of the tank...these are for something like overflow from the tank and also a breather hose (so as the tank uses fuel it doesn't cause a vacuum as air can still get in the tank).

    That should now be everything off the tank and it should just pull up and out.

    Hopefully your fuel connectors have sealed. You'll know if they haven't as fuel will be glugging out the tank. There may be a little fuel dribble out the fuel lines on the bike. Lay the tank down on some blankets or towels or whatever to protect it.

    Do what you need to do.

    Refitting is pretty much the reverse.

    All the connectors can only go in one place and only one way round.
    You know which fuel line goes where... From your photo.
    The two little rubber hoses are easier to put on when the tank is off the bike (if they came off).

    Jiggle the tank back into place.

    Torque everything back up.

    Kinda done!

    It's good housekeeping to ensure those little rubber hoses on the nipples are clear/unblocked.

    It's erudite to get some little rubber o rings for the fuel lines as you may damage them when you disconnect which will mean you have a fuel leak when reconnection. They cost pennies.
    If you have the plastic fuel connectors you can change them for metal ones, which are easy to fit (therell be a link for that along shortly I'm sure).

    First time this all seemed a bit of a worry...now it's less than 10 mins.

    I hope this was the level of detail you wanted otherwise I've written this in bed in the dark for no reason and kept my rubber mallet awake unnecessarily.

    Hiya...I can not quite remember, and I am not entirely sure what the requirements are regarding size, and petrol resistance. These issues may or may not be as important as I worry they are; but just in case hopefully someone will be along in a moment with the appropriate link!

    From memory they cost a couple of pounds for quite a few - which is always handy in case you nick one when trying to refit/undo the hoses again. For what it is worth, by the time I had finished with the various tank removals and and attaching/taking off the hoses I was quite good at no longer nicking them! But it took me a couple before I "got it", so a few spare is no bad thing.

    What about the actual connectors, plastic or metal?
