Tonight, I did the layout and drilled the holes in the ribs and cap sender plates for the right auxillary tank. My plan is to use cap sender plates in all tanks, with the option to install floats in the main tanks as a backup. Additionally, I plan to have a fuel flow sensor and EFIS fuel totallizer, which will calculate remaining fuel. All this, plus tracking fuel burn and time, should give me an accurate estimate of fuel remaining at all times.
