It can be tricky, but it squeezes right out. I found it easier to remove the tank, although, at a slightly later date, when I changed the fuel lines, I put slightly longer lines back on, only about a inch or so longer, so that any ‘under tank’ work can be done without having to disconnect it. Just move it back, then lift to the left, and support it with a ‘bungy’ cord. When replacing it, silicone around each inlet rubber, then replace at a slight tilt towards you,then push in and down till upright. There’s a bit of a knack to it.
