That matches my recollection. Also, correcting my previous comment, Pluto was 2" and 3" pipes, not 9". That is, the vast majority of oil used in Allied operations in Europe passed through a set of 2- and 3-inch pipes, with 17 laid in total per the Wikipedia article I'd linked earlier. Which speaks both to the flow-rates achieved (~400,000 Imperial gallons/day), and the energy content of petroleum.
