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

The Facet Solid State Fuel Pump 40105 is a compact, low-current 12V electric pump that reliably delivers up to 30 gallons per hour for engines up to about 180 HP while running on gasoline, ethanol blends (including E85), diesel and biodiesel.

This single-pump solution is engineered for vehicles and equipment with modest fuel demands where quiet, efficient delivery and broad fuel compatibility matter. With solid-state internals instead of diaphragms or seals, the 40105 keeps electrical draw low (roughly 1 amp at 12V) and provides steady low-pressure flow for carbureted or fuel-injected systems that require up to 3–4.5 psi maximum pressure.

How much fuel flow and pressure can I expect from this pump?

The Facet 40105 can supply up to 30 gallons per hour at its maximum flow rating, and typical delivery is about 20 gph at 2 psi. Maximum operating pressure ranges between approximately 3 and 4.5 psi, making it suitable for low-pressure fuel systems and aftermarket conversions.

• Maximum flow: 30 GPH (gallons per hour)
• Typical flow: ~20 GPH at 2 psi
• Maximum pressure: 3–4.5 psi
• Ports: 1/8" NPT female inlet and outlet

Will this pump work with modern fuel blends like E85 or biodiesel?

Yes — the Facet 40105 is compatible with gasoline, ethanol blends up to E85, diesel and biodiesel, as well as common fuel additives. Its materials and solid-state design reduce the risk of degradation when exposed to blended fuels.

• Safe for ethanol blends including E85
• Compatible with diesel and biodiesel
• Resistant to common fuel additives and detergents
• No rubber diaphragms that degrade from alcohol exposure

What are the electrical and installation considerations?

The pump draws very little current — about 1 amp at 12 volts — so it’s easy to power from most vehicle electrical systems without heavy wiring. Keep in mind the 40105 has no internal check or anti-siphon valve, and it can allow fuel to flow back through the pump when switched off.

• Operating voltage: 12V DC, ~1 amp draw
• No internal check/anti-siphon valve — external valve recommended if needed
• Maximum vertical dry lift: 12 inches
• Use 1/8" NPT fittings for inlet/outlet plumbing

How does this pump compare in durability and origin?

Facet electronic fuel pumps are designed and manufactured in the USA to high quality standards and are new, not remanufactured. They meet or exceed OEM specifications for fit and performance, making them a reliable replacement for many low-flow applications.

• Designed and made in the USA
• Meets or exceeds OEM fit and performance specs
• New unit — not remanufactured
• Solid-state construction reduces moving parts and wear points

Who is this for: The Facet-Purolator 40105 is ideal for hobbyists, classic car restorers, light-duty marine applications, small engines and conversions that need a dependable low-pressure pump with broad fuel compatibility. Choose this unit when you want a compact, low-current pump that handles ethanol blends and biodiesel while fitting typical low-flow systems where a 12-inch dry lift and modest pressure are sufficient.
