Full model list at the end of this description.

## ⚙️ Key Features

-   Genuine Volvo Penta fuel-system vent hose
-   Fuel-resistant construction
-   Preformed for the designated D13 installation
-   Helps prevent trapped air within the fuel system
-   Maintains correct routing away from heat and moving components
-   Suitable for propulsion, auxiliary and generating-set D13 engines

## 🔌 Function

The hose vents trapped air or fuel vapour through the intended fuel-system path. A sealed and unobstructed vent connection helps maintain stable fuel delivery and prevents air from being drawn into the system.

## ⚠️ Common Signs of Failure

-   Diesel fuel seepage around the hose or fittings
-   Strong fuel odour in the engine compartment
-   Visible cracking, hardening or swelling
-   Air entering the fuel circuit
-   Extended cranking or difficult starting
-   Unstable engine operation after filter servicing
-   Wetness around the vent-hose connections

## 🛠️ Service Notes

-   Weighs 0.181 kg and is the D13-specific vent hose - Volvo Penta lists several hoses of different lengths under this same fitting, so measure or confirm the routed length against your engine's parts list rather than ordering by name alone
-   Keep the fuel-resistant hose clear of hot exhaust components and moving parts along its route, exactly as specified for the D13 fuel system
