⚙️ 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
