21153852 Fuel Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta formed fuel hose for a model-specific marine diesel fuel circuit. This reference is identified in Volvo parts systems as replaced by later service components, so the current replacement configuration must be selected from the complete engine product and serial number.

⚙️ Key Features

• Genuine Volvo Penta earlier fuel-hose reference
• Model-specific bore, end fittings and routing geometry
• Later service replacement can be split or revised
• Part-number and selection
• Inspect mating pipes, banjo fittings and sealing washers during replacement
• Engine type: Volvo Penta marine diesel fuel system

🔌 Function

Transfers diesel fuel through the assigned circuit while maintaining sealed flow and the original routing clearance.

⚠️ Common Signs of Failure

• Diesel seepage, fuel odour or wet fittings
• Air entering the low-pressure circuit and causing hard starting
• Cracking, fretting or fatigue near bends, clamps or unions
• Restricted return or supply flow
• Fuel-pressure faults, unstable idle or reduced engine performance

🛠️ 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
