One tank run completely empty and filled up with exactly 6 gallons of fuel, hour meter at 13.4 hrs. Ran the 72" Super Z HyperDrive until the tank was completely emptied with the hour meter now at 17.7 hrs.
This equated to 17.7 - 13.4 = 4.3 hrs. run-time...6 gallons of fuel used Ă· by 4.3 hrs. run-time = 1.39 gph
The 72" Super Z HyperDrive with the Vanguard 37 hp EFI on the second check used 1.39 gallons of fuel per hour...This is very impressive when pulling a 72" deck and the industrial grade HyperDrive hydraulic system carrying 3 gallons of oil.
For all those that believe their in not that much difference between a closed-loop and open-loop EFI system, this completely disproves your belief
