Mr. Gasket Fuel Injection Pumps: Race-Proven Fuel Delivery

When consistent fuel delivery is the difference between a winning pass and a stumble off the line, performance builders have long turned to Mr. Gasket. Founded in 1964 by drag racer Joe Hrudka — who used his own '57 Chevy as a rolling test bed — the brand was built from the ground up on the demands of real-world racing. Today, as part of the Holley Performance family of brands, Mr. Gasket continues to engineer fuel system components that enthusiasts and professionals rely on for power and reliability.

The Micro Electric Fuel Pump Lineup

Mr. Gasket's core offering in the fuel injection pump category is its well-regarded Micro Electric Fuel Pump series — a compact, universal lineup engineered to handle a broad range of fuel types and engine configurations. The series spans several application-specific models, giving builders the right pump for their exact fuel chemistry and platform:

• Model 12S – Designed for standard gasoline applications, compatible with gasoline-based fuels and additives.
• Model 12D – A diesel-specific variant delivering 4–7 PSI at 35 GPH, featuring a gravity-fed, self-priming two-wire design and an included 100-micron in-line filter.
• Model 12E – Built for methanol, ethanol, E85, and race fuel applications, rated at 4–7 PSI and 35 GPH for demanding alternative-fuel builds.
• Model 42S – Tailored for import vehicle applications.
• Model 95P / 105P – Higher-output options for engines with greater fuel demands.

Engineering That Makes a Difference

What sets Mr. Gasket Micro Electric pumps apart is their practical, installer-friendly engineering. These self-priming pumps operate on a 12-volt negative-ground system and draw approximately one amp at maximum delivery — keeping electrical load minimal even in stripped-out race cars. The solid-state electronics are designed to be worry-free, and the simple two-wire hookup means installation is straightforward regardless of your plumbing situation. Fittings and mounting hardware are included, so there's no hunting for extras once the pump arrives.

The pumps also work effectively as both stand-alone units and booster pumps, and they are specifically engineered to eliminate two of the most frustrating fuel system gremlins: vapor lock and flooding. For builds where reliable fuel pressure is non-negotiable — whether on the strip or the street — that kind of dependability matters.

A Heritage Backed by Racing

Mr. Gasket's fuel delivery products don't exist in isolation. The brand's deep roots in drag racing and circle track competition mean every component is developed with real performance conditions in mind. Beyond fuel pumps, the broader Mr. Gasket catalog includes carburetor and fuel system components, engine gaskets, shifter accessories, and engine dress-up parts — all engineered with the same performance-first philosophy that has defined the brand for more than six decades.

Whether you're feeding a high-compression V8 on pump gas, running E85 on a modified import, or converting a diesel to an electric fuel pump setup, Mr. Gasket's fuel injection pump lineup offers a solution designed to deliver consistent pressure, build after build.
