🔌 Function

Carries fluid or air between two components as a flexible section of the engine's plumbing, absorbing the movement between the points it connects.

⚠️ Common Signs of Failure

• Weeping, staining or dried residue around a joint or under a clamp
• Hose that has gone hard and glassy, or soft and spongy, when squeezed
• Cracks in the outer cover, swelling or ballooning, or a section that collapses under suction
• Coolant loss, or air being drawn into the system, with no leak visible outside
• Smell of fuel or exhaust in the engine space, or fresh rub marks where the hose has moved against something

🛠️ Service Notes

• Fit hoses only to clean, sound spigots — take off old rubber, scale and corrosion, and renew the spigot or pipe if it is pitted, because no clamp will seal a rough sealing face
• Push the hose fully home so the clamp sits behind the bead or barb rather than over the end of the spigot, and fit new clamps whenever a hose is renewed
• Let the hose follow its natural bend with no kinks and no tension on either connection, clear of hot surfaces and moving parts, with chafe protection wherever it passes a bracket, edge or bulkhead
• Use the correct grade of hose for the duty, and clamp to the standard the installation demands — twin clamps are normal practice on seawater and fuel connections below the waterline
• Refill, vent and run the engine, then check every joint hot and cold and recheck the clamps after the first running period as the hose beds down
