The Fuel Pump for a 454 Mercruiser is a marine-specific mechanical pump designed to deliver consistent fuel flow to the engine. It ensures reliable performance under harsh marine conditions, including corrosion resistance. Compatible with Mercruiser 454 engines, it maintains optimal fuel pressure for smooth operation.

The Fuel Pump for a 454 Mercruiser typically has the following key specifications and technical properties:

Size: Approximately 6-8 inches in length, 4-5 inches in width, and 3-4 inches in height.

Grade: Marine-grade, designed for inboard/outboard (I/O) applications.

Viscosity: Compatible with fuels ranging from 10W-30 to 20W-50 engine oil viscosity.

Buoyancy: Not applicable (non-buoyant, as it is a mechanical/electrical component).

Material: Housing made of corrosion-resistant aluminum or stainless steel; internal components include rubber diaphragms, stainless steel springs, and brass fittings.

Pressure Rating: Typically 4-7 psi for carbureted engines.

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

Compatibility: Designed for gasoline (ethanol blends up to E10).

Mounting: Bolt-on or bracket-mounted, depending on the model.

Electrical (if applicable): 12V DC operation with waterproof connectors.
