Available now on the Airparts.aero Marketplace.

Overview

The Continental Motors 649364-2 is a genuine OEM, engine-driven, dual-diaphragm fuel pump, engineered for Continental's high-performance, fuel-injected 520 and 550-series engines. This flight-critical component is a highly advanced mechanical pump designed for maximum safety and reliability. It features a redundant dual-diaphragm system to prevent fuel from contaminating the engine oil, and an integral vapor return port to eliminate vapor lock. This pump is designed to draw fuel from the tanks and deliver it at a consistent high pressure to the engine's fuel control unit, ensuring reliable engine performance in all flight regimes.

Key Features

• Dual-Diaphragm Safety System: The pump's primary safety feature is its dual-diaphragm design. Two independent diaphragms separate the fuel chamber from the engine crankcase. Should the primary diaphragm fail, fuel is captured in a central chamber and safely routed out an overboard vent line, providing a clear indication of a fault while preventing catastrophic mixing of fuel and oil.
• Integral Vapor Ejector / Return: Features an additional port for a vapor return line. This allows superheated fuel vapor, which can form in the pump body during hot-and-high operations, to be purged from the system and returned to the fuel tank. This is a critical feature for preventing vapor lock and ensuring consistent engine operation.
• High-Pressure Output: Specifically designed for fuel-injected engines, this pump delivers a consistent fuel pressure required by the fuel control unit for proper fuel metering, ensuring the engine can produce its full rated horsepower.
• Engine-Driven Reliability: Actuated mechanically by a dedicated lobe on the engine's camshaft, it provides a robust and reliable fuel supply that is independent of the aircraft's electrical system, forming the core of the primary fuel system.
• Genuine Continental OEM Part: As a genuine factory component, it guarantees perfect fitment, correct pressure delivery, and conformance to the stringent quality and safety standards required by the original engine Type Certificate.

Technical Specifications

• Part Number: 649364-2
• Component Type: Engine-Driven, Dual-Diaphragm Fuel Pump with Vapor Return
• Pressure Rating: High Pressure
• Actuation Method: Mechanical Camshaft Lobe
• Safety Features: Overboard vent port for leak indication; vapor return port for anti-vapor lock.
• Certification: FAA Production Approval

Aircraft Compatibility

The 649364-2 is the specified OEM high-pressure fuel pump for a wide range of aircraft powered by Continental's premier large-bore, 6-cylinder engines. It is imperative to consult the specific engine's Illustrated Parts Catalog (IPC) for final verification.

• Common Continental Engine Series:
  • IO-520, TSIO-520
  • IO-550, TSIO-550
• Common Aircraft Platforms:
  • Beechcraft: Bonanza, Baron
  • Cessna: 206, 210, 310, 340
  • Mooney: M20 series (with Continental engines)

Applications

The 649364-2 is the heart of the primary fuel delivery system for high-performance fuel-injected engines:

• Primary Fuel Delivery: Its main function is to draw fuel from the tanks and deliver it under constant high pressure to the fuel control unit.
• Engine Overhaul: A critical component that is typically replaced or overhauled during any major engine overhaul to ensure system reliability.
• Fuel System Troubleshooting: The primary component to inspect when diagnosing issues of low or fluctuating fuel pressure during engine operation (with the electric boost pump off).

Why Choose 649364-2?

The fuel delivery system must be absolutely reliable for safe flight. The Continental 649364-2 pump incorporates two critical design features—the dual-diaphragm and vapor return—that are essential for the safety and reliability of high-performance piston aircraft. Using a genuine Continental OEM pump ensures that you are installing a component with the correct, factory-set pressure relief values, the proper materials to resist modern aviation fuels, and the robust construction needed to endure millions of pressure cycles. For a component this vital, there is no substitute for a genuine factory part.

The 649364-2 fuel pump's vapor return system is a key feature for preventing vapor lock, a dangerous condition where fuel turns to vapor in the lines, causing a loss of fuel pressure and engine stoppage. On hot days, heat from the engine can cause the fuel inside the pump to boil. The vapor return line creates a continuous, small bleed path from the top of the pump's swirl chamber back to the fuel tank. This allows any accumulated vapor bubbles to be purged from the system, ensuring that only solid liquid fuel is delivered to the fuel control unit. The dual diaphragm provides a redundant safety barrier. The space between the two diaphragms is vented to an overboard line, so if the fuel-side diaphragm develops a leak, liquid fuel will be seen dripping from the vent, providing a clear pre-flight indication of an impending pump failure.

Note: This is a flight-critical engine component. Installation must be performed by a certified A&P mechanic in strict accordance with the current Continental Motors maintenance and overhaul manuals. Proper installation requires careful alignment of the actuating arm with the pushrod in the accessory case. Always use a new gasket upon installation.
