Mr. Gasket 12S Micro Electric Fuel Pump — 12V 35 GPH Compact Self-Priming Pump with 4–7 PSI, Includes Fittings

Mr. Gasket 12S Micro Electric Fuel Pump is a compact 12-volt, two-wire self-priming pump that delivers 35 GPH for carbureted domestic 4-, 6-, and 8-cylinder engines.

This compact, gravity-fed unit is designed for simple installation and reliable fuel delivery on negative-ground 12V systems. It provides a steady flow at 4–7 PSI, includes fittings and mounting hardware, and averages about a 1 amp draw at maximum output. The Mr. Gasket 12S is built for classic cars, hot rods, restorations, and auxiliary fuel-transfer needs where a small, efficient pump is preferred over larger electric units.

How easy is it to install the 12S Micro Electric Fuel Pump?

Installation is straightforward thanks to its two-wire design and included hardware. The pump suits gravity-fed systems and requires a negative-ground 12V electrical connection; no complex plumbing or control modules are necessary.

• Includes mounting brackets, fittings, and DIY instructions for quick setup.
• Two-wire hookup reduces wiring complexity—connect power and ground only.
• Compatible with common carburetor inlet sizes on domestic engines.

What performance can I expect from this pump in daily use?

The 12S provides consistent fuel flow up to 35 gallons per hour at a pressure range of 4–7 PSI, suitable for most stock carburetor applications. It is self-priming and designed to minimize issues like vapor lock on warm engines.

• Flow rate: 35 GPH at recommended operating pressure.
• Pressure range: 4–7 PSI to match carburetor fuel bowls.
• Electrical draw: roughly 1 amp at full delivery for efficient power use.

Will this pump work for fuel transfer and overflow prevention?

The Mr. Gasket 12S functions well as a fuel transfer pump and helps reduce vapor lock and flooding by maintaining steady pressure. Its small footprint makes it suitable for auxiliary transfer tasks or as a replacement for older mechanical pumps in restoration projects.

• Effective for short-distance fuel transfer and tank-to-vehicle topping.
• Reduces vapor lock risk through consistent flow at typical operating temperatures.
• Self-priming action simplifies restart after idle or refueling.

Who is this for? The Mr. Gasket 12S Micro Electric Fuel Pump is aimed at vehicle restorers, hot-rod builders, hobbyists, and mechanics needing a compact, reliable electric pump for carbureted domestic engines. It’s especially appropriate where simplicity, low electrical draw, and included installation hardware matter—such as classic cars, show vehicles, or as an auxiliary transfer pump in garages.
