yes sir....always my pleasure and appreciate the acknowledgement which is extremely rare on here.
YES....you simply remove the rear tire and the lower shock mount from the swingarm and drop the arm down to its lowest postion. see the vid below. it's the best i've found and the first 5 minutes or so show removal. every XB fuel pump has to be wiggled and cajoled a bit to come out but it will.
when replacing it be sure to smear a light coat of either O-ring silicone lube OR chrysler style lubri-plate lube onto the 2 housing O-rings....then install. if not done the O-rings tend to tear when you slide the pump into the frame spar.
if you can't source the fuel level sensor over in Olde Blighty let me know and i'll send you one over. USPS first class air is $14 to anywhere in the UK.
here ya go.....
