ENGINEMAN 12V Electric Fuel Pump for Carbureted Engines — Super 12S Plus 5–9 PSI, 35 GPH

ENGINEMAN Super 12S Plus is a universal 12-volt electric fuel pump engineered to deliver stable 5–9 PSI and up to 35 GPH for carbureted gasoline and diesel engines.

This compact, high-performance pump is built for muscle cars, classic restorations, race fuel cells, and auxiliary tanks where consistent pressure and reliable flow matter. Designed for most 4-, 6- and 8-cylinder carburetor setups, the Super 12S Plus combines a copper-wound motor, vibration-dampening housing, and a pressure-stabilization system so engines avoid lean conditions during hard acceleration. The package includes a mounting bracket, inline fuel filter, hoses, wiring and a clear wiring diagram to simplify DIY installations.

How does this pump keep fuel pressure steady under load?

The Super 12S Plus uses a pressure-stabilization design and optimized impeller geometry to maintain 5–9 PSI even during high-RPM demand. That steady pressure helps prevent momentary fuel starvation or lean spikes when throttle is opened aggressively.

• Pressure range: 5–9 PSI suitable for most carbureted setups.
• Flow capability: up to 35 GPH (approx. 130 L/H) for reliable delivery.
• Copper-wound motor reduces voltage fluctuation and keeps current draw low (1–2 A).
• Mounting orientation retains fuel internally for immediate restart readiness.

What is included and how easy is installation?

ENGINEMAN supplies a full installation kit to make mounting and wiring straightforward for hobbyists and professional installers alike. The pump is designed to be installed within 12 inches of the fuel tank and the kit includes hoses, filter, bracket and instructions to get the job done quickly.

• Complete kit: mounting bracket, fuel filter, two 5/16" flex hoses, and wiring (red/black).
• Hardware and step-by-step instructions for sub-30-minute DIY installation in many cases.
• Recommended mount: upward 45° to retain internal fuel between startups.
• Clear wiring diagram reduces guesswork and installation errors.

Can I use this pump for fuel transfer or with performance fuel systems?

The Super 12S Plus doubles as an efficient gasoline transfer or booster pump for race fuel cells, auxiliary tanks, and garage fuel transfers. With a low current draw and 35 GPH flow, it handles quick transfer tasks while minimizing heat and electrical load.

• Transfer rate: 35 GPH is suitable for auxiliary tank refills and race cell priming.
• Low draw: roughly 1.0–2.0 A helps avoid battery strain during operation.
• Not compatible with ethanol blends like E85, methanol, or water-based liquids—designed for pure gasoline.
• Vibration-dampening design reduces noise during transfer and pumping.

How does ENGINEMAN ensure durability and quiet operation?

The pump’s copper-wound motor and vibration-reduction construction extend service life while limiting noise and minimizing voltage drops. Every unit is subjected to a 24-hour endurance test so buyers receive a product that has already passed basic operational checks.

• Copper-wound motor for stable electrical performance and longer life.
• Vibration-dampening housing reduces operational noise and wear.
• 24-hour endurance testing before shipment verifies basic reliability.
• Designed to prevent vapor lock and flooding in typical gasoline applications.

Who is this for?

The ENGINEMAN Super 12S Plus is aimed at enthusiasts and mechanics who need a compact, reliable electric fuel pump for carbureted vehicles, performance builds, and fuel-transfer tasks. It’s ideal for classic cars, hot rods, race support setups, and auxiliary fuel systems where a stable 5–9 PSI, moderate 35 GPH flow, and an easy-install kit are required. Avoid this model if you intend to pump ethanol blends, methanol, or water-based liquids.
