Facet-Purolator 12V Cylindrical Fuel Pump Red Top - 1/4 NPT, 45 GPH, 6-8 psi

The Facet-Purolator Facet 480532N Red Top is a 12V cylindrical electronic fuel pump that delivers up to 45 gallons per hour with a built-in 6–8 psi relief, designed for engines requiring higher fuel volume up to ~350 hp.

This compact, high-output pump combines lightweight design with solid-state electronics and an internal 74-micron filter to supply consistent fuel flow for gasoline, alcohol blends (including E85), diesel, biodiesel, and common additives. Engineered and manufactured in the USA to meet OEM fit and performance expectations, the Red Top model replaces older Bendix/Facet numbers and runs on negative-ground 12V systems with minimal current draw (around 1 amp).

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

The Red Top pump is rated for a maximum delivery of 45 gallons per hour (GPH) and typically produces about 38 GPH at 2 psi. Maximum pressure is specified in the 6 to 8 psi range, with an internal relief that prevents flooding after engine shutdown.

• Maximum flow: 45 GPH
• Typical flow: ~38 GPH at 2 psi
• Maximum pressure: 6–8 psi with built-in relief
• Includes internal 74-micron filtration

Will this pump work with my fuel type and engine application?

Facet-Purolator designed this pump to be compatible with a wide range of fuels and additives, making it suitable for many street and race applications. It supports gasoline, ethanol blends up to E85, diesel and biodiesel, plus common fuel additives—avoid use on systems requiring anti-siphon features unless an external valve is added.

• Compatible fuels: gasoline, E85, diesel, biodiesel
• Accepts common fuel additives
• No built-in anti-siphon valve — fuel may flow when power is off
• Dry lift: up to 24 inches vertical

How does installation and electrical hookup work for this pump?

The Facet 480532N uses 1/4" NPT female ports for inlet and outlet fittings and requires a negative-ground 12V electrical system. Solid-state internal electronics replace older mechanical points, reducing maintenance and improving reliability. The pump draws roughly 1 amp at 12 volts, so it’s easy on vehicle electrical systems.

• Ports: 1/4" NPT female inlet and outlet
• Electrical: negative-ground 12V only, ~1 amp current draw
• Solid-state electronics (no points or diaphragms)
• Compact cylindrical form for versatile mounting

What reliability and service considerations should I know?

Facet-Purolator manufactures these pumps in the USA to meet or exceed OEM specs and does not sell remanufactured units in this line. The solid-state design eliminates many failure points of older pumps; however, buyers should beware of counterfeit units and confirm genuine Facet part numbers when replacing older models.

• Made in the USA to OEM-level standards
• Not remanufactured — new electronic internals
• Replaces older Bendix/Facet 480558 and listed as 480532(E) in some references
• Check authenticity to avoid unreliable knock-offs

Who is this for: The Facet 480532N Red Top is aimed at vehicle builders, performance enthusiasts, and shop technicians who need a compact, high-volume auxiliary or primary fuel pump for applications up to roughly 350 horsepower. It’s a good choice where low electrical draw, solid-state reliability, compatibility with ethanol or diesel blends, and a compact footprint are priorities. If you require an anti-siphon feature or a different pressure range, consider adding an external valve or selecting a model matched to those needs.
