Fuel pumps on boats are essential for transferring fuel from tanks to engines efficiently. Marine pumps are designed to withstand harsh saltwater environments and ensure reliable performance. They come in various types, including mechanical, electric, and diaphragm pumps, tailored for different marine applications.

Size: Typically ranges from 1/4 inch to 2 inches in diameter, depending on the boat size and fuel system requirements.

Grade: Marine-grade fuel pumps designed to meet ASTM, ISO, or SAE standards for marine applications.

Viscosity: Compatible with fuels ranging from gasoline (low viscosity) to diesel (higher viscosity), typically handling 1-6 cSt.

Buoyancy: Not applicable to fuel pumps; buoyancy is a property of float switches or fuel tank components.

Material: Constructed from corrosion-resistant materials such as stainless steel, aluminum, or reinforced plastics.

Flow Rate: Varies between 30-300 liters per hour (LPH) based on pump capacity.

Pressure Rating: Typically operates between 3-10 psi for most marine fuel systems.

Power Supply: 12V or 24V DC, compatible with marine electrical systems.

Temperature Range: Designed to function in -20°C to 80°C (-4°F to 176°F) environments.

Certifications: Often complies with USCG, ABYC, or CE marine safety standards.

Seals: Viton or nitrile rubber for fuel resistance and durability.

Mounting: Can be inline or submerged, depending on the fuel tank design.
