I'm not saying my pump installation is ideal but they are located on the floor in front of the main spar in the cockpit. My wing tanks are in the outer wing panels so the bottom of the tanks are approx at pump level. The incoming lines are routed over the main spar. My pumps have nevered failed to prime even with no fuel in the lines as in starting with empty tanks. I tested a spare pump before installing and was able to pull water approx 30 inches vertical starting with an empty line. As always, your results may vary. Do your own testing on your system. Don't even consider going to the runway without first performing a flow test on the fuel system. Minimum is 1.5 times the max fuel burn for your engine in any attitude. I fugured my max burn at 7 gal per hour so 10.5 gal per hour would be my minimum. I'm getting approx 30 gph with my pump(s) and would indicate the pumps are putting out their rated GPH.
