Full model list at the end of this description.

⚙️ Key Features

• Genuine fuel-filter housing closure
• Factory thread and seating geometry
• Helps prevent fuel leakage and air entry
• Suitable for Volvo Penta 16-litre fuel systems listed below
• Individual cap/plug; filter housing and seals are separate unless supplied
• Engine type: Volvo Penta 16.1-litre inline six-cylinder diesel

🔌 Function

Seals the designated opening in the fuel-filter housing so the low-pressure fuel circuit remains closed, clean and free from air ingress.

⚠️ Common Signs of Failure

• Fuel seepage around the cap
• Hard starting caused by air entering the fuel system
• Damaged or crossed threads
• Missing, flattened or hardened sealing element
• Contamination entering during service

🛠️ Service Notes

• Clean and inspect the seating face on the housing as well as the cap — most leaks past a cap are the seat or the seal rather than the cap body
• Renew any separate O-ring or gasket that goes with the cap, and lubricate rubber seals lightly with clean oil or grease so they slide home instead of rolling or tearing
• Do not over-tighten a cap into a plastic or aluminium housing; it seals on its gasket or O-ring, not on force, and stripped threads mean a much bigger repair
• Where a cap blanks a port during a repair, keep it fitted right up to the moment of assembly so nothing enters the opening
• Check the cap is fully home and that any retaining clip, lanyard or locking tab is secure before returning the boat to service
