FB Jets Dolphin S
developed in the fuel system. All fuel system lines should be properly inserted onto the tubing and
safety wire tied to prevent unwanted and potentially harmful leaks.
Note:
Restriction in the fuel system may cause performance issue with your turbine such as not
allowing proper full speed RPM, abnormally high pump pulse width numbers and or excessive
stress placed on the tanks while fueling the model. Stress on the tanks is due to expansion caused
by air not venting out of the tanks fast enough during fueling. Additionally fuel restrictions or leaks
on the suction side of the fuel pump can cause cavitation, leading to air ingestion in the turbine fuel
supply, ultimately causing a flame out.
Total Fuel System Volume of the supplied tanks with the prototype was 135 oz (4000 ml)
Saddle Tanks ea. : 34 oz. (1000 ml)
Main Tank: 68 oz. (2000 ml)
Larger diameter tubing and drilled out tank hardware, Fuel line barbs soldered onto the tubes
Factory supplied saddle and main tanks.
