Q: Is 4.8 mm fuel hose resistant to high temperatures and fuel degradation?

A: Yes, 4.8 mm fuel hoses designed for fuel resistance and high-temperature applications use reinforced synthetic rubber or fluoropolymer materials, typically enduring temperatures up to 120°C (248°F) while maintaining chemical stability.

Q: Can a 4.8 mm fuel hose be used for fuel injection systems?

A: Yes, specialized 4.8 mm fuel hoses rated for fuel injection systems withstand higher pressures (up to 10 bar/145 psi) and ensure precise fuel delivery without leaks or swelling.

Q: Is a 2-inch fuel filler hose compatible with 4.8 mm fuel hose connections?

A: No, 4.8 mm (≈0.19-inch) hoses require adapters for 2-inch fuel filler systems due to significant diameter differences. Use purpose-built 2-inch hoses for filler neck applications.

Q: What makes high-temperature fuel hoses suitable for 4.8 mm applications?

A: High-temperature 4.8 mm fuel hoses feature multi-layer construction with heat-resistant liners and abrasion-resistant outer covers, ensuring safe operation in engine bays or near exhaust components.

Q: How does a 4.8 mm fuel injection hose differ from standard fuel hoses?

A: Fuel injection hoses have tighter tolerances (4.8 mm ID), reinforced walls, and low-permeability layers to handle pressurized modern injection systems, unlike basic vent or low-pressure hoses.
