Facet 12V Solid State Fuel Pump 40105 — 30 GPH Low-Current, E85-Compatible

This solid-state pump delivers dependable low-pressure fuel transfer for engines roughly up to 180 horsepower. Designed without diaphragms or traditional seals, the Facet 40105 uses an electronic pumping mechanism that keeps electrical draw minimal (around 1 amp at 12 volts) and reduces routine maintenance. It is engineered to work with gasoline, alcohol blends including E85, diesel, biodiesel, and common fuel additives.

How much fuel flow and pressure can I expect from the 40105?

The 40105 can provide a maximum flow rating near 30 gallons per hour under ideal conditions, with typical operation around 20 GPH at low system pressure. Working pressures are intentionally low to suit fuel delivery and transfer applications rather than high-pressure injection systems.

• Maximum reported flow: up to 30 gallons per hour
• Common operating flow: ~20 GPH at approximately 2 psi
• Usable pressure range: about 3 to 4.5 psi maximum

Which fuels and environments is this pump compatible with?

The pump is chemically tolerant to a broad set of fuels, making it versatile for automotive, marine, and small machinery uses. Its construction accepts gasoline, diesel, biodiesel, and alcohol-containing fuels up to E85, plus most aftermarket fuel additives used for everyday operation.

• Safe with gasoline and diesel formulations
• Compatible with blended alcohol fuels including E85
• Accepts biodiesel and common fuel conditioners or additives

How does installation and plumbing work with this pump?

The Facet 40105 uses 1/8-inch NPT female ports for inlet and outlet connections, and it does not include an internal check or anti-siphon valve. That means fuel can flow freely through the unit when it is not powered, so system design should account for possible backflow or siphoning.

• Ports: 1/8" NPT female for inlet and outlet fittings
• No built-in check or anti-siphon valve—external valve recommended if backflow is a concern
• Maximum dry lift: about 12 inches vertical under dry conditions

What are the power requirements and durability features?

The 40105 runs at 12 volts and draws very little current—typically around 1 amp—making it suitable for vehicles and projects where electrical load is limited. Facet builds these pumps in the USA to meet or exceed OEM expectations, and this model is supplied new (not remanufactured).

• Voltage: 12 V DC operation
• Low current draw: roughly 1 amp at 12 V
• Manufactured in the USA to OEM-level quality standards

Who is this for? The Facet Solid State Fuel Pump 40105 is ideal for hobbyists, builders, and technicians needing a compact, low-power pump for fuel delivery on small engines, classic cars, hot rods, small boats, generators, or custom fuel systems that operate at low pressure. It suits installations that require broad fuel compatibility and minimal electrical draw, provided your system accounts for its lack of an internal check valve.
