[QUOTE="teejay, post: 76473, member: 51"] no worries dude..... :rolleyes: and yes you are correct about the uneven shape of the tank, but the sending unit sends whatever it measures, so its up to the gauge to decipher the signals, its both a combo of logarithms, exponential and linear equats........ i tried measuring the various signals at various levels, and it didn't make sense, coz i tot it was a linear measure...... :blink: the red light that comes on for reserve is at a certain level and at a certain resistance, and that's set and very much accurate coz there's not much left........ it's also not recommended that the fuel pump is run too long without the fuel around it, especially those with in-tank, coz it will heat up easily and its life will be very much shorten [/QUOTE]
