Per Bob Barrows, the engine max BSFC is less than .50 lb. This would require 21.67 gal/hr at 100% power. 21.67 gal.hr x 150% = 32.5 gal/hr required for test.
Made three test with fuel selector on BOTH. Started with 5 gallons in each tank for minimal fuel.
BOTH Test #1 = 40.4 gal/hr BOTH Test #2 = 35.6 gal/hr BOTH Test #3 = 35.3 gal/hr
