It can be a little awkward to remove. After removing the side panels & undoing the tank retaining bolts I prop the tank up with the the plate at the bottom of the tank (the chap in this video uses a block of wood but the silver plate, just above it, is the tool for the job) then remove the electric connection & breather pipes. The video doesn't make in clear, but to remove the feed pipe you just squeeze the blue 'tags' together & pull the two parts away from each other. The technique is to ensure they are being pulled straight, any slight movement will make it difficult. It's the same replacing the fuel line, push them together as straight as possible and ensure you hear or feel a click when the tags seat.
There may be other YouTube videos, this was one of the first I came across.
