21530025 Bowl | Genuine Volvo Penta Part

🔧 Product Description

Lower fuel-filter bowl used on Volvo Penta TAD12 industrial and generator engines. The bowl forms the collection chamber beneath the filter head or element, allowing water and heavy contamination to settle away from the fuel outlet and providing the original mounting location for the associated drain or water-detection equipment.

⚙️ Key Features

• Genuine Volvo Penta fuel-filter bowl
• Transparent/collection-bowl function for fuel and water separation
• Used on TAD1240-TAD1252 engine families
• Original sealing, drain and sensor interface
• Cross-referenced to Volvo heavy-equipment bowl applications
• Engine type: 12.1-litre inline-six turbocharged diesel

🔌 Function

Collects separated water and contamination beneath the fuel filter and maintains a sealed lower chamber for clean fuel delivery.

⚠️ Common Signs of Failure

• Fuel leakage around the bowl seal
• Cracked, clouded or impact-damaged bowl
• Water-in-fuel contamination not draining correctly
• Damaged drain or sensor mounting threads

🛠️ 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
