# 21486648 Fuel Hose | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine low-pressure fuel hose replacing earlier Volvo Penta hose 3828660.

## ⚙️ Key Features

-   Diesel-fuel-resistant construction
-   Factory-specified bore and length
-   Replaces 3828660
-   Suitable for fuel supply or return service as assigned

## 🔌 Function

The hose transfers diesel fuel between the assigned filter, pump, tank or return connection.

## ⚠️ Common Signs of Failure

-   Fuel seepage
-   Air entering the system
-   Hose cracking or swelling
-   Fuel odour
-   Unstable engine operation

## 🛠️ Service Notes

-   Renew the sealing washers, O-rings or seals that belong to the connection rather than reusing them, and do not put jointing compound on a fuel union to cure a weep
-   Fit the hose without twist, and support and clip it along its run so it cannot chafe or hang its own load on the end fittings
-   Keep the hose clear of hot exhaust and moving parts, and cap the open ends while working so nothing gets into the fuel system
-   Tighten unions to the figure given in the workshop manual for your engine — overtightening a fuel fitting distorts the seat and makes the leak permanent
-   Bleed the fuel system afterwards, then run the engine and check the whole run for weeps under working pressure, with no ignition sources near and a means of containing spilt fuel to hand
