Parts for Caterpillar 3512 – Fuel Section

The Caterpillar 3512 engine is a powerhouse designed for the most demanding applications—marine propulsion, industrial power generation, oilfield operations, and heavy-duty equipment. To keep an engine of this caliber running at peak efficiency, maintaining a clean and properly primed fuel system is essential. At the heart of that system is the fuel priming pump, a small but critical component that ensures smooth and reliable fuel delivery to the injectors before startup. Diesel Pro Power offers two precision-engineered Caterpillar fuel priming pumps for the 3512 engine, each designed to meet OEM standards and deliver dependable performance in the toughest conditions.

Caterpillar Fuel Priming Pump – 188.4cc Stroke per Lifter

This heavy-duty Caterpillar fuel priming pump is built for high-volume applications and features a 188.4cc stroke per lifter, providing strong and consistent fuel delivery. Its design ensures rapid priming of the 3512’s fuel system after maintenance, filter replacement, or long periods of inactivity. The larger stroke capacity helps eliminate trapped air pockets and quickly restores proper fuel pressure, which is crucial to prevent injector damage and ensure reliable starts.

Built using precision-machined components and corrosion-resistant materials, this pump is engineered to perform in harsh environments—whether mounted on marine propulsion systems, standby generators, or industrial equipment. Operators appreciate its sturdy construction and long service life, which translate to fewer maintenance interruptions and more consistent fuel system performance over time.

Caterpillar Fuel Priming Pump – 76.6cc Stroke per Lifter

The second model available for the 3512 engine features a 76.6cc stroke per lifter, offering a slightly smaller displacement while maintaining excellent efficiency and reliability. This version is ideal for installations where compact size and quick manual priming are desired. Despite its smaller size, it delivers smooth fuel delivery and rapid air evacuation, making it a preferred choice for auxiliary systems, generators, and support equipment powered by the 3512 engine.

Each pump is tested to ensure precise fuel flow and proper sealing, preventing leaks and maintaining pressure stability under high vibration and heat. Whether used for daily operations or as a reliable backup priming unit, this pump provides peace of mind for operators who depend on their engines to start without fail.
