You are right Richard - no warning lights on VDO Cockpit Vision guages. However, they might end up being just a distraction - with the long shallow fuel tanks, I find that I get readings from full to empty, just going up or down long hills on part-full tanks - even with baffles in the tanks. The only time that the setup is accurate is when I am stopped on level ground, or going at a constant speed on a level road !
Kind Regards,
