4. Setup and Installation
Follow these steps to properly install the YMT Extended Run Fuel Gas Cap:
- Prepare the Brass Fitting: Ensure the brass hose fitting is clean and free of debris. The fitting has a 1/4" male NPT thread on one end and a 1/4" barbed fitting on the other.
- Attach Fitting to Cap: Carefully thread the brass hose fitting into the center opening of the extended run fuel gas cap. Hand-tighten first, then use a wrench to secure it firmly, ensuring a snug fit without overtightening. The cap features an internal sealing mechanism to prevent leaks.
- Remove Existing Generator Cap: With the generator turned off and cooled, carefully remove the existing fuel cap from your generator's fuel tank.
- Install Extended Run Cap: Screw the assembled YMT Extended Run Fuel Gas Cap onto your generator's fuel tank opening. Ensure it is securely tightened to prevent fuel leaks.
- Connect External Fuel Line: Attach a compatible plastic or rubber fuel hose (with a 1/4" inside diameter) from your external fuel tank to the barbed end of the brass fitting on the extended run cap. Secure the hose with a clamp if necessary to ensure a tight, leak-free connection.

5. Operating Instructions
Once the YMT Extended Run Fuel Gas Cap is installed and connected to an external fuel tank:
- Ensure all connections (cap to generator, hose to cap, hose to external tank) are secure and leak-free before operating the generator.
- The extended run system allows the generator to draw fuel from the external tank, significantly increasing its operational duration.
- Always monitor fuel levels in both the generator's internal tank and the external tank.
- When disconnecting, ensure the generator is off and cooled. Disconnect the external fuel line first, then remove the extended run fuel cap.
6. Maintenance
To ensure optimal performance and longevity of your YMT Extended Run Fuel Gas Cap:
- Regular Inspection: Periodically inspect the fuel cap and brass fitting for any signs of wear, damage, or corrosion.
- Cleanliness: Keep the cap and fitting clean. Wipe away any fuel spills immediately.
- Seals: Check the internal sealing mechanism for integrity. If any part appears compromised, replace the unit to prevent fuel leaks.
- Storage: When not in use for extended periods, store the cap in a clean, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fuel Leakage | Cap not tightened sufficiently; damaged seal; loose hose connection. | Ensure cap is securely tightened. Inspect internal seal for damage and replace if necessary. Check hose connections and secure with clamps. |
| Generator not drawing fuel from external tank | External fuel line kinked or blocked; improper connection; external tank empty. | Check fuel line for obstructions. Verify all connections are correct. Ensure external fuel tank has fuel. |
