## ⚙️ 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
