Got mine from Demon Tweaks £50.46 delivered with neoprene gasket, fitted 3 weeks ago. http://www.demon-tweeks.co.uk/motorsport...-for-vdo-gauge. Its better than before but still erratic, at 200 miles got 35 litres in when showing about 10%. At 235 miles 29 litres showing 4%. I still zero the trip on filling.
