As the leading ship supplier in Ross Dependency, Crusader Ra080018, we specialize in delivering high-quality Mercruiser 5.7 Fuel Line with unmatched speed and reliability. Trusted by shipowners and masters worldwide, our team ensures your vessel gets everything it needs — on time, every time.
The Mercruiser 5.7 fuel line delivers gasoline from the tank to the engine, ensuring proper fuel flow. Marine pumps, including fuel and water pumps, are designed to withstand harsh marine environments. These components are critical for reliable engine performance and durability in boating applications.
The Mercruiser 5.7 fuel line typically uses 3/8-inch inner diameter (ID) hose, made from marine-grade SAE J1527 A1 or A2 compliant materials for fuel resistance. Fuel lines are often constructed from nitrile rubber (NBR) or other oil-resistant synthetic rubber with reinforced layers for durability. Marine fuel pumps for the 5.7L engine usually deliver 50-60 psi (3.4-4.1 bar) and have a flow rate of 30-40 gallons per hour (GPH). Viscosity requirements depend on fuel type (e.g., gasoline or ethanol blends), with recommended viscosities per OEM specifications. Buoyancy is not typically a specified property for fuel lines, but marine-grade hoses are designed to resist water absorption and degradation. Materials must meet USCG, ABYC, and NMMA standards for marine use.
