The fully electronic engines pump huge quantities of fuel to help cool the fueling system. Our Tier 2, 2009 QSB 5.9 burns 2.5gph at 7.2kt. The fuel pump is pushing 50 GPH! Cheers, Tom 410.212.7898

I haven't measured with precision but my 1964 Cat D330-TA, nothing electronic about it, appears to pump over 40 gals/hour and burns 2 to 7 depending on how hard I push it. My normal "cruise" is about 1350 rpm and about 3 g/h. I have done rough measurements by pulling from one tank and returning to the other and verified that excess return was in the vicinity of 40 g/h. I believe I saw a spec for the fuel pump somewhere that said something about pumping 40 g/h, but I probably couldn't find that again.
