10AN 402 Series Push Lock Hose 3ft Black

The 10AN 402 Series Push Lock Hose 3ft Black is a professional-grade fuel and coolant line designed for serious engine builders, modified vehicles, and high-performance fuel systems. Whether you're upgrading a carbureted hotrod, installing a modern EFI retrofit, or fabricating custom cooling lines, this hose delivers the reliability and ease of installation that separates shop-quality builds from amateur work. Push lock fittings eliminate the need for clamps and hose barbs, saving time during assembly while providing a cleaner, more secure connection under pressure.

Built with reinforced synthetic rubber and rated for fuel, coolant, and compatible fluids, the 10AN 402 Series hose features REDHORSE PERFORMANCE's proven push lock design that grips fittings securely without slipping or weeping. The 10AN bore (5/8-inch OD equivalent) handles significant flow rates required by fuel pumps, turbo cooling circuits, and intercooler setups in modified engines. At 3 feet in length, this hose spans typical engine bay distances—from fuel tank to carb, pump to filter, or radiator to block—while the black exterior resists UV degradation and blends seamlessly into modern engine compartments. Lightweight at 0.645 lbs and compact in storage, it's ideal for kit builds and replacement applications.

This hose suits street rods, LS swaps, fuel-injected restorations, turbocharged builds, and any custom application where AN fittings are already in place. Mechanics and fabricators favor push lock hose for rapid prototyping and final assembly because it seats instantly and requires no crimping tools or specialized training. Pair it with matching 10AN push lock fittings to create a leak-free fuel or coolant loop that withstands both street driving and track use. Check your existing line routing and fitting size before ordering to ensure compatibility with your engine's fuel delivery or cooling system.
