Easy!

done this not long ago on mine.

pipes are plastic from the filler neck, but they change to rubber half way down to go onto the tank end so shouldnt break if your carefull.
watch the wires clipped round the pass side of the tank.
filler pipes are rubber and plastic, the ring clips might be rusted so new ones are an idea.
good idea as said to get it on a pair of ramps, drive on ones are fine.
remember and swap the small breather at the top over, thin, thin pipe.

I thot my tank was more or less empty but got around 5-6litres out of it once i took it off

sender - might be tight on, but chap it with a flat screwdriver and a hammer, working your way round it and it should come off np!
