How many gallons per hour do you figure that engine takes to run?

For some reason that doesn't look like a GE T-38. You sure that's a
GE engine and not the Lycoming T-53 or the French version of the T-53
(which was a very popular engine in Europe).

Figure about 1 gph for every 7 or 8 actual horsepower developed. Maybe
about 120 gph at full power?

Golly, not even my old pair of 454s burned that much!
