21408351 Filter Insert | Genuine Volvo Penta Part

🔧 Product Description

Replaceable primary diesel fuel-filter and water-separator element used across established Volvo Penta TAD, TD and generating-set engine families. The element removes particulate contamination and separated water before fuel reaches the injection system, and is the later Volvo service replacement for filter insert 20430640.

⚙️ Key Features

• Genuine Volvo Penta primary fuel-filter insert
• Fuel/water-separator type filtration element
• Protects injection pumps and injectors from water and abrasive contamination
• Direct service replacement for earlier Volvo insert 20430640
• Broad industrial and generating-set application with exact housing fitment controlled by engine model
• Engine type: Volvo Penta inline industrial diesel with primary fuel/water separation

🔌 Function

Filters diesel fuel and separates entrained water before the fuel reaches the engine's fine filtration and injection equipment.

⚠️ Common Signs of Failure

• Hard starting or loss of power under load
• Restricted-fuel or low-supply-pressure symptoms
• Visible water or contamination in the filter bowl
• Uneven running caused by inadequate fuel flow
• Service interval exceeded or filter media contaminated

🛠️ Service Notes

• Renew the insert as a unit at the service point for your engine — a filter element is not something to clean out and put back, and washing one drives trapped dirt through to the clean side
• Make sure the old sealing ring has come out with the old element; a doubled-up seal left in the housing is one of the commonest causes of a leak or a filter that will not prime after a service
• Fit the new seals and O-rings supplied with the insert, lightly lubricated with the fluid the filter is handling unless the manual for your engine says otherwise
• Fit the element the right way round and seat it fully on its spigot before closing the housing, then tighten the cover or bowl to the manual figure — plastic housings are easily split by overtightening
• Prime or bleed the housing as the manual describes, then run up and check for leaks and for correct pressure or flow before leaving the boat
