Hand Fuel Pump Bulb AWTools AW16032 — 10 mm Fuel Hose Connection

The AWTools hand fuel pump bulb AW16032 is a compact, manually operated pump designed for transferring fuel and priming small engines without electrical power. Its squeeze bulb body made of flexible rubber and a 10 mm hose connection make it suitable for inline fuel transfer, bleeding carburettors, and topping up small tanks. The pump is lightweight, portable and intended for simple fuel line maintenance tasks where a small, reliable manual solution is required.

Advantages

The rubber squeeze bulb provides a tactile, controllable pumping action for accurate fuel transfer. A standard 10 mm hose connection allows compatibility with common fuel hoses and easy installation in-line. The unit's simple construction requires no external power and is easy to store and transport. Its compact size reduces clutter in toolkits and onboard storage while enabling targeted priming and suction in confined spaces.

Suitable for

• Priming outboard motors and inboard small boat engines
• Transferring fuel between small containers and tanks
• Bleeding carburettors and fuel lines on lawn mowers and garden machinery
• Emergency fuel transfer and on-site maintenance where electric pumps are impractical

Key specifications

• Connection diameter: 10 mm hose interface for common fuel tubing
• Body material: flexible rubber bulb for manual compression
• Operation: hand-operated squeeze pump, non-electric
• Application: designed for liquid fuel transfer and priming small engines
• Portability: compact and lightweight for storage in toolboxes and marine compartments

How to use

Attach a compatible 10 mm fuel hose securely to the pump's hose connection and position the other end in the source and destination containers or fuel fittings. Squeeze the rubber bulb repeatedly to create suction and move fuel through the hose; maintain a steady rhythm until the desired amount of fuel is transferred or the engine is primed. After use, depress the bulb to expel any residual fuel back into a safe container or the tank, then disconnect and store the pump in a well-ventilated area away from heat and open flame.

Usage recommendations

Use compatible fuel-rated hoses and clamps for a secure connection. Perform transfers in a well-ventilated environment and avoid sparks or open flames. Rinse the bulb with a small amount of clean fuel-compatible solvent if cross-contamination with different fuel types is a concern, and inspect the rubber for wear or cracking before each use.
