3. Package Contents
- Hangar 9 Ultra Fuel Pump (Manual Gas & Glow)
- Rubber Tubing (approximately 3 feet)
- Metal Filter
- Spout
4. Setup Instructions
- Attach Tubing: Connect one end of the provided rubber tubing to the inlet port of the fuel pump. Ensure a secure connection to prevent leaks.
- Install Filter: Attach the metal filter to the other end of the inlet tubing. This filter should be submerged in the fuel container.
- Connect Spout: Connect the spout to the outlet port of the fuel pump. This spout will direct fuel into your model's tank.
- Priming the Pump: Before first use, or if the pump has been stored dry, it may need to be primed. Submerge the filter end of the inlet tubing into fuel and operate the pump handle until fuel begins to flow consistently through the spout.

5. Operating the Fuel Pump
- Prepare for Fueling: Place the filter end of the inlet tubing into your fuel supply container. Position the spout into the fuel tank of your model aircraft.
- Pump Operation: Rotate the crank handle clockwise to pump fuel from the supply container into your model's tank. The pump is designed with overdrive gearing for efficient transfer.
- Reversible Function: The pump is reversible. Rotating the handle counter-clockwise will draw fuel out of the model's tank and back into the supply container, which is useful for defueling after use.
- Fuel Volume Estimation: Approximately three (3) full turns of the handle equate to one (1) ounce of fuel transferred. Use this as a general guide for monitoring fuel volume.
- Post-Fueling: Once fueling is complete, remove the spout from the model's tank and the filter from the fuel supply. Secure all components.
6. Care and Maintenance
- Cleaning: After each use, especially when switching between different fuel types (e.g., gasoline and glow fuel), it is recommended to purge the pump. Run a small amount of the new fuel type through the pump to clear any residue from the previous fuel.
- Storage: Store the fuel pump in a clean, dry environment away from direct sunlight and extreme temperatures. Ensure all tubing is clear of obstructions.
- Inspection: Periodically inspect the tubing and connections for any signs of wear, cracks, or leaks. Replace damaged components immediately.
- Lubrication: The internal gears are designed for long-term use. Avoid disassembling the pump unless necessary for repair by a qualified technician.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not draw fuel / No fuel flow | Pump not primed; Air leak in tubing/connections; Filter clogged; Tubing kinked or obstructed. | Ensure pump is primed by operating it with the inlet submerged in fuel. Check all connections for tightness. Clean or replace filter. Straighten tubing. |
| Fuel leaks from pump or connections | Loose connections; Damaged tubing; Internal seal issue. | Tighten all tubing connections. Inspect tubing for cracks and replace if damaged. If internal leakage persists, contact Hangar 9 support. |
| Pump handle is difficult to turn or seized | Internal debris or fuel residue buildup; Mechanical failure. | Attempt to flush the pump with clean fuel. If the issue persists, the pump may require professional servicing or replacement. |
