#4 Hose 3'

The AEROQUIP #4 Hose 3' is a braided stainless steel and rubber racing hose assembly engineered for high-pressure hydraulic and fuel line applications in performance and motorsports environments. This 4 AN (1/4-inch) hose delivers reliable fluid transfer with the durability required in demanding engine bay conditions where temperature, pressure, and vibration continuously test component integrity.

Constructed with braided stainless steel reinforcement over a high-quality rubber core, the AEROQUIP FCA0403 hose resists corrosion, maintains flexibility across thermal cycles, and withstands the pulsing pressure common to fuel injection systems, brake lines, and power steering circuits. The natural rubber exterior is compatible with most automotive fluids and provides genuine abrasion resistance during installation and routing around engine components. At 3 feet in length, this hose offers practical reach for mid-size engine bay layouts without unnecessary excess, and the 4 AN connection size matches common fuel rail, carb feed line, and cooler line applications.

This hose is designed for builders and technicians working on custom fuel systems, racing platforms, and restoration projects where OEM hose routing or capacity is insufficient. AEROQUIP's racing hose line is trusted in both circle track and road course environments where pressure cycling and heat exposure demand materials rated well beyond street-use minimums. The individual hose unit allows point-to-point system assembly without committing to pre-made harness kits.

Proper hose routing and support with clamps every 12–18 inches are essential to prevent vibration-induced wear. Always verify your system's working pressure against the hose rated specification before installation to ensure safe operation.
