1. Technical Specifications

2. Key Features

• High-Impact & UV-Resistant HDPE Shell: Seamless rotational/blow-molded construction offers superior puncture resistance, structural stiffness, and protection against solar degradation.

• Built-In Mechanical Fuel Gauge: Top-mounted direct-reading fuel meter provides real-time fuel level tracking (E - 1/2 - F) without requiring electrical wiring.

• Manual Venting Gas Cap: Features a precision two-way breathing screw to relieve internal vacuum during engine operation and seal tightly to prevent vapor loss during storage.

• Deep Pickup Tube with Pre-Filter: The extended internal suction tube reaches the bottom sump, fitted with a high-mesh brass strainer to prevent large sediment and debris from entering the fuel line.

5. Common Symptoms & Troubleshooting

• Engine Starvation or Stalling at Cruising Speed:

• Cause: Gas cap vent screw remains closed (causing vacuum lock), or the bottom pickup strainer is clogged with fuel debris.

• Troubleshooting: Loosen the cap vent screw counterclockwise before starting; inspect and clean the pickup tube mesh filter.

• Fuel Leaks or Air Sucking at the Quick Connector:

• Cause: Worn O-rings inside the mating hose socket or damaged male plug pins on the tank housing.

• Troubleshooting: Inspect the male outlet fitting for fuel weepage; replace worn fuel line connectors or tank outlet adapters.

• Severe Tank Swelling or Collapsing:

• Cause: Exposure to heat with the vent closed, or a clogged two-way vent valve.

• Troubleshooting: Crack open the vent screw during high-temperature outdoor storage to equalize pressure. Replace permanently deformed tanks.
