Just installed flush fuel caps with the fuel gauge and it has no hints on what different amounts of lights mean  it comes with 8 lights so i assume thast means 1/8th per light  so i have been riding and with 2 lights still lit up it started to miss like it was out of fuel, anyone got and info to share on the readings of these caps ???

When all little lights are lit your tank is full. When there are no little lights lit, your tank is empty. Tank is partially full/empty when little lights are in between all and none. They look good and should be an oem item.
