⚙️ Key Features

• Genuine Volvo Penta moulded inlet-system hose
• Factory bend, bore and length
• Used with the specified filter and non-return valve arrangement
• Resistant to oil mist and engine-room heat
• Direct replacement for a split or hardened original hose
• Engine type: 5.5L inline six-cylinder common-rail turbocharged marine diesel

🔌 Function

Carries filtered air or crankcase-ventilation flow through the inlet-system filter and non-return-valve arrangement.

⚠️ Common Signs of Failure

• Air or oil-mist leakage
• Hose cracking, hardening or collapse
• Loose clamps
• Unfiltered-air entry
• Restricted ventilation or intake flow

🛠️ 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
