Setup
Before operation, ensure all components are present and undamaged. The setup process involves connecting the appropriate fitting to your carburetor and then attaching the gauge assembly.
- Identify Carburetor Port: Locate the vacuum or pressure test port on your small engine carburetor. Consult your engine's service manual for specific port locations.
- Select Fitting Tube: Choose one of the three provided fitting tubes that best matches the size of your carburetor's test port.
- Connect Fitting Head: Attach the brass fitting head to one end of the selected fitting tube.
- Connect Oil Pipe: Connect the oil pipe (flexible hose) to the other end of the fitting tube assembly.
- Attach Gauge: Connect the free end of the oil pipe to the inlet port of the pressure gauge assembly. Ensure all connections are secure to prevent air leaks during testing.

Operating Instructions
This gauge is designed to test for leaks in small engine carburetors by applying pressure or vacuum. Follow these steps for accurate testing:
- Prepare Carburetor: Ensure the carburetor is clean and accessible. Depending on the test, you may need to block certain ports or remove fuel lines.
- Connect Tester: Securely connect the assembled leak detector to the carburetor's test port as described in the Setup section.
- Apply Pressure/Vacuum: Use an external pump (not included) to apply a small amount of pressure or vacuum to the carburetor through the gauge. The gauge will display the pressure or vacuum level.
- Monitor Reading: Observe the gauge reading. A stable reading indicates no significant leaks. A drop in pressure or loss of vacuum indicates a leak.
- Identify Leak Source: If a leak is detected, use a leak detection spray or listen for hissing sounds to pinpoint the exact location of the leak (e.g., gaskets, diaphragms, seals).
- Disconnect: Once testing is complete, carefully disconnect the gauge and fittings from the carburetor.

Maintenance
Proper maintenance ensures the longevity and accuracy of your Zerodis Carburetor Leak Detector Pressure Gauge.
- Cleaning: After each use, wipe down the gauge and fittings with a clean, dry cloth. If necessary, use a mild, non-abrasive cleaner. Avoid harsh chemicals that could damage the materials.
- Storage: Store the kit in a clean, dry place, away from direct sunlight and extreme temperatures. Keep all components together to prevent loss.
- Inspection: Periodically inspect the hoses and fittings for cracks, wear, or damage. Replace any damaged components immediately to maintain accurate readings and prevent leaks during testing.
Troubleshooting
If you encounter issues while using your leak detector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Gauge shows no reading or erratic reading. | Loose connections; blocked hose/fitting; damaged gauge. | Check all connections for tightness. Inspect hoses and fittings for blockages or damage. If the gauge is damaged, it may need replacement. |
| Cannot maintain pressure/vacuum. | Leak in the system (carburetor or tester components); improper sealing. | Re-check all connections. Ensure the fitting tube is correctly seated in the carburetor port. Inspect hoses and fittings for cracks or holes. The carburetor itself may have a significant leak. |
| Difficulty connecting to carburetor. | Incorrect fitting tube size selected. | Try a different size fitting tube from the kit that provides a snug fit. |
