Emptying tank and fitting a new one?

im going to be swapping my fuel tank for a less dented one that the bike came with.

whats the easiest way to get fuel out of the old tank? should i do it while its still on the bike or after its off?

is there any special procedure for filling the new tank? can the vacume line get air in it during swapping over?

any help apriciated, dont want fuel ****ing out all over!! ( her indoors wont be happy )

The tank will come off without spilling fuel but you might as well run it down as empty as you can first.

Keep the fuel cap closed. Remove the front seat, lift the tank, disconnect the hoses from the fuel tap and the drain under the tank and disconnect the fuel sensor. Then lower the tank and remove the hinge bolts at the rear of the tank. Lift the tank off - no petrol will come out. If you're in the garage/shed, take it outside for the next stage.

I just needed to get most of the fuel out of mine so I just opened the fuel cap and turned the tank upside down over a big funnel into a petrol can. I presume you'll be taking the fuel tap off the bottom rear of the tank to refit to your new one? If so you can get the fuel out there when you take the tap off and then you can decant it into your petrol can.

If you're anything like me you'll likely splash a bit of petrol when decanting in to the can, so do it outdoors. And put your fag out first.

cheers for the advice matey, i managed to swap it over in my lunch break today!
spilt a bit of petrol on the floor but at least it wasnt my garden/shed/kitchen!!

cheers again

I took my tank off, balanced on a large bucket then kept priming the fuel pump (FI) until 99% of the fuel had come out, worked pretty well.
