Facet Cube 12V Fuel Pump Kit FEP289SV (1/8 NPT) — 32 GPH, 4–7 psi low-pressure

Facet FEP289SV is a compact 12‑volt solid‑state low‑pressure fuel pump kit designed to deliver up to 32 gallons per hour with a controlled 4–7 psi maximum pressure for moderate engine fuel systems.

This complete Facet Cube pump kit is built for light to medium fuel demands — typically engines up to about 150 horsepower — and offers resilient service across a wide range of fuels including gasoline, diesel, biodiesel, and alcohol blends up to E85. The solid‑state design minimizes electrical draw (around 1 amp at 12 V), eliminates vulnerable diaphragms and seals, and includes a built‑in pressure relief to prevent over‑pressurization after shutdown. The kit comes with the Facet 40289 pump, mounting hardware, and adapters to accept 5/16" fuel hose, making it ready to fit many retrofit and replacement applications.

How does the Facet FEP289SV fit into moderate fuel systems?

The Facet Cube pump supplies steady, low pressure ideal for gravity‑fed or returnless carbureted and fuel‑injected setups that require modest flow. It’s sized for smaller engines and auxiliary systems, providing reliable supply without the bulk or power demands of high‑pressure pumps.

• Maximum delivery: 32 gallons per hour, suitable for engines up to ~150 hp.
• Typical operation: about 15 GPH at 3 psi for common low‑pressure needs.
• Compact footprint simplifies installation in tight engine bays or equipment compartments.

What fuels and additives can this pump handle?

The Facet Cube is engineered for broad chemical compatibility so you can run common fuels and blends without premature degradation. Solid‑state construction resists breakdown from alcohols and modern additives that can harm older pump designs.

• Compatible with gasoline, diesel, biodiesel and alcohol blends up to E85.
• Accepts standard fuel additives used for cleaning and stability.
• Recommended for applications where fuel variety or ethanol content may vary.

How safe and convenient is installation and operation?

The kit includes the pump (Facet part number 40289), mounting hardware, and hose adapters for 5/16" fuel lines to make fitting straightforward. Electrical connections are simple: negative lead with ring terminal and a bare positive lead ready for an inline connector or splice.

• 1/8" NPT female ports for plumbing versatility with standard fittings.
• Built‑in pressure relief prevents post‑shutdown flooding on hot engines.
• Built‑in check valve ensures one‑way fuel flow (note: not an anti‑siphon valve).

What are the performance limits and installation notes?

The pump is intended for low‑pressure service; it is not a high‑pressure EFI pump. It achieves a 60" dry lift rating and performs best when mounted within reasonable distance of the fuel source and on a stable bracket. Because the pump’s check valve is not an anti‑siphon device, take precautions if siphoning is a concern.

• Maximum pressure range: 4–7 psi (factory specification).
• Typical flow: 15 GPH at 3 psi; max flow 32 GPH at low backpressure.
• Does not include anti‑siphon valve — use external anti‑siphon if required by your system.

Who this is for: Technicians, home mechanics, and OEMs seeking a compact, energy‑efficient low‑pressure pump for small engines, classic cars, farm equipment, or portable machinery will appreciate the Facet FEP289SV Cube kit. It’s particularly well suited for projects that need compatibility with ethanol blends or biodiesel and where a small electrical load and simple plumbing are priorities. If your application demands high fuel pressure or a pump with anti‑siphon features, consider a different model or add complementary components to meet those needs.
