DB Electrical Facet POSI-FLO Solid State Fuel Pump 12V 15 GPH — Self-Priming, Vapor-Lock Resistant

The DB Electrical Facet POSI-FLO™ Solid State Fuel Pump is a 12V, 15 GPH self-priming pump designed to provide consistent, vapor-lock-resistant fuel delivery for lawn-and-garden and small-engine applications.

This compact, solid-state pump replaces traditional mechanical diaphragm units with an electronic design that removes moving electrical contacts and flexible diaphragms. Built to meet OEM-style specifications and compatible with a wide range of fuels, it helps maintain steady flow and restart reliability in hot weather and at altitude. Verify fitment against your equipment specifications before installing.

How does this pump prevent vapor lock and improve hot-weather performance?

The POSI-FLO design maintains continuous fuel flow without relying on fragile rubber diaphragms, reducing the chance of vapor bubbles forming in the line. Its self-priming capability and a built-in pressure relief feature help avoid flooding and ensure reliable restarts after heat exposure. These attributes make it useful for equipment that operates in warm climates or climbs to higher elevations.

• Solid-state operation eliminates electrical contact wear that can contribute to inconsistent flow.
• Self-priming action reduces manual priming needs during restarts.
• Pressure relief prevents flooding and aids dependable restarts after shutdown.
• Specifically rated to eliminate vapor lock in common lawn-and-garden use cases.

What are the installation and electrical connection details?

This pump uses a 1/8-27 internally threaded fuel fitting and standard 6.6mm ID ring terminal negative lead for straightforward wiring. It runs on 12 volts and is constructed for compatibility with common small-engine fuel systems; check that thread types and flow capacity (15 GPH) match your equipment. The unit is designed for easy service and a direct aftermarket swap for listed OEM part numbers.

• Fitting type: 1/8-27 internally threaded for common hose/adaptor setups.
• Electrical: 12V operation with negative lead using a 6.6mm ID ring terminal.
• Flow: 15 gallons per hour (GPH), suitable for lawn-and-garden engines and similar applications.
• Replaceable for OEMs: Arrowhead FPF-60304N, Atlas Copco 4812269806, Facet 60304.

Which fuels and environments is this pump compatible with?

The pump is formulated to accept a wide variety of fuels including leaded and unleaded gasoline, diesel blends, pure alcohol, and many fuel additives. Its corrosion-resistant plastic housing provides extended resistance to salt spray and environmental exposure found in outdoor equipment. While robust, always confirm chemical compatibility for specialty fuels before prolonged use.

• Compatible with leaded/unleaded gasoline, diesel, blended fuels, and pure alcohol.
• Plastic casing engineered for over 100 hours of salt spray resistance in testing.
• Suitable for outdoor, lawn-and-garden equipment operating in humid or coastal settings.
• Avoid long-term exposure to fuels or additives not specified by the pump manufacturer.

What are the pump’s pressure and performance specs?

The POSI-FLO model provides a maximum shutoff pressure of about 2 PSI and a minimum shutoff pressure of 1 PSI, with a minimum dry lift capability of 50 inches (127 cm). It includes a check valve to maintain fuel column integrity but does not include a positive shutoff or quiet valve. These performance figures make it suitable for small-engine fuel delivery where moderate pressure and lift are required.

• Flow rate: 15 GPH to support small-engine fuel demands.
• Shutoff pressures: min 1 PSI, max 2 PSI for controlled delivery.
• Dry lift: minimum 50 inches (127 cm) for effective self-priming from low-sump conditions.
• Includes a check valve; positive shutoff and quiet valve are not included.

Who is this for: The DB Electrical Facet POSI-FLO™ pump is aimed at owners and technicians of lawn-and-garden equipment, small engines, and light industrial machines who need a reliable 12V fuel pump that resists vapor lock and is easy to install. It's a fit-for-purpose aftermarket replacement for specific OEM numbers, suitable for those who want a durable, corrosion-resistant option with self-priming and pressure-relief features. Always confirm thread fittings, electrical connections, and fuel compatibility with your machine before purchase.
