📋 Kit Contents

• 1 x complete fuel-filter gasket kit - Volvo Penta 21018758
• 2 x sealing rings - Volvo Penta 20460248

🔌 Function

The rings seal the filter head and separator bowl so fuel remains contained and air cannot enter the low-pressure fuel circuit.

⚠️ Common Signs of Failure

• Diesel fuel seeps from the bowl or filter head
• Fuel system loses prime
• Hard starting after filter service
• Water-separator bowl has been removed
• Seals are cut, swollen or permanently flattened

🛠️ Service Notes

• Check the kit contents against the joints you are actually opening before you start, and lay the parts out so nothing is left in the bag
• Renew every gasket in the kit as a set; a used gasket has already taken its crush and will not seal a second time
• Clean the mating faces properly without gouging them — a plastic or hardwood scraper and a solvent are safer than a steel blade, especially on aluminium
• Fit gaskets dry unless the workshop manual for your engine specifies a sealant, and then use only the sealant it names
• Tighten the joint evenly in the sequence and to the figures given in the manual for your engine, and re-check after the first heat cycle where the manual calls for it
