20870050 Bowl | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta lower bowl for the specified fuel-filter or water-separator assembly. The bowl forms the collection chamber beneath the filter element, allowing separated water and heavier contamination to settle away from the fuel outlet while providing the original sealing and drain interfaces.

⚙️ Key Features

• Genuine Volvo Penta Fuel Filter / Water Separator Bowl - part number 20870050
• OEM bowl geometry for the specified filter head and element
• Provides a collection volume for separated water and sediment
• Correct sealing diameter and thread or retaining interface
• Supports the original drain plug, sensor or valve where fitted
• Fuel-compatible construction for continuous diesel exposure
• Inspect the bowl, seal and drain hardware whenever the filter is serviced
• Engine type: Fuel-filter and water-separator assemblies

🔌 Function

Fuel entering the filter assembly slows and changes direction, allowing water and dense contamination to settle into the bowl. The bowl keeps this material below the clean-fuel outlet until it is drained during routine service.

⚠️ Common Signs of Failure

• Fuel leakage around the bowl seal or drain
• Cracked or damaged bowl body
• Water-in-fuel warning returns immediately after draining
• Drain valve will not seal
• Bowl threads or retaining lugs no longer hold correctly

🛠️ Service Notes

• Renew the O-rings and seals that belong with the bowl whenever it is disturbed, and check each one is seated in its groove before the bowl is drawn up
• Wet the seals with clean fuel or a smear of oil before assembly so they slide into place rather than rolling or pinching
• Tighten the bowl only as the procedure for your engine describes, by hand where specified — over-tightening distorts and cracks a bowl, and a cracked bowl puts fuel into the bilge
• Check the drain tap or plug is closed and sealing, then fill and bleed the fuel system working from the tank end forward
• Check the bowl joint for weeping with the system pressurised and the engine running, and drain off accumulated water at the intervals in your engine's service schedule
