The 1996 Mercruiser 5.7 fuel pump is a marine-specific mechanical pump designed for reliable fuel delivery in boating applications.

It ensures consistent fuel pressure to the engine, crucial for optimal performance in marine environments.

Built to withstand corrosion and harsh conditions, it is a durable component for Mercruiser 5.7L engines.

The 1996 Mercruiser 5.7 fuel pump is a mechanical diaphragm-type pump. Key specifications include:

Size: Approximately 4.5 inches in diameter and 3 inches in height.

Grade: Designed for marine gasoline engines (87-93 octane).

Viscosity: Compatible with fuels meeting ASTM D4814 standards.

Buoyancy: Not applicable (non-submersible design).

Material: Housing is typically cast aluminum or steel; diaphragm is nitrile rubber or similar fuel-resistant elastomer.

Pressure Output: 4-6 psi (typical for carbureted applications).

Flow Rate: ~30-40 gallons per hour (GPH).

Mounting: Bolt-on, engine-mounted (driven by camshaft eccentric).

Compatibility: Fits Mercruiser 5.7L (350 CID) engines with carbureted fuel systems.
