# 21618090 Hose | Genuine Volvo Penta Part

## 🔧 Product Description

A colour-coded diagnostic and fluid-routing hose used in the TWD1663GE injector test or measurement system. This black hose is 4500mm long and runs from injector to pump.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TWD1663GE

-   **Engine Family:** TWD

## ⚙️ Key Features

-   Colour identification: Black
-   Nominal length: 4500mm
-   Routing: from injector to pump
-   Factory-fitted connections for the TWD1663GE test arrangement
-   L=4500mm (Volvo assembly listing)

## 🔌 Function

The hose transfers test fuel or fluid from injector to pump while its colour and length prevent incorrect connection during diagnosis or servicing.

## ⚠️ Common Signs of Failure

-   Fuel or test-fluid leakage
-   Cracked or hardened hose
-   Damaged end fittings
-   Incorrect routing or colour connection
-   Restricted flow caused by kinking

## 🛠️ 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
