Interesting question, I asked the same one a couple of months ago after disconnecting the lines from my multi tank without marking which one went where. It doesn't matter as the line is just a continuous loop that feeds fuel to the injectors... there's no check valves or anything that would require the flow to go in one particular direction.I come across this image from manual and noticed that my fuel lines are reversed where they connect to the fuel pump. What can happen?
That seems low considering that I am getting 150Km before the yellow light with the race ECU on a GT1000 (Both GT1000 and Sport 1000 are supposed to have the same fuel consumption and tank capacity).I thought that was the culprit for the high fuel consumption. 100Km per tank, untill the yellow light starts to flicker.
