## ⚙️ Key Features

-   Genuine Volvo Penta formed fuel hose
-   Current replacement for 21300622
-   Catalogued in D3 marine fuel systems
-   Correct fuel-resistant material and factory end connections
-   Supports reliable priming and low-pressure fuel flow
-   Hose only; filter, water-in-fuel sensor, seals and fittings are separate

## 🔌 Function

Carries diesel fuel through the low-pressure side of the D3 fuel system while preventing external leakage and air entry.

## ⚠️ Common Signs of Failure

-   Diesel smell or visible wetness
-   Hard starting or loss of prime
-   Air bubbles in the supply line
-   Cracking, hardening or swelling
-   Chafing at brackets or clamps
-   Uneven running caused by air ingress

## 🛠️ 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
