20754813 Overflow Valve | Genuine Volvo Penta Part

🔧 Product Description

Brand-new genuine Volvo Penta fuel-system overflow valve for selected TAD16 engines. The calibrated valve maintains the specified low-pressure fuel-gallery or return pressure and allows excess fuel to flow back through the return circuit. Correct pressure calibration and connection arrangement are critical to starting and engine performance.

⚙️ Key Features

• Calibrated genuine fuel overflow/return valve

🔌 Function

Controls fuel return flow to maintain the designed pressure in the low-pressure fuel circuit and releases excess fuel back to the tank or return manifold.

⚠️ Common Signs of Failure

• Long cranking or difficult hot restarting
• Low power or unstable idle from inadequate supply pressure
• Fuel-pressure fault codes
• Fuel leakage around the valve or banjo connection
• Excessive return flow or restricted return circuit

🛠️ Service Notes

• Treat it as a sealed, non-adjustable unit — renew it rather than attempting to clean, shim or adjust the internals
• Work clean: cap the openings, wipe the area down before opening the fuel system, and do not let dirt or fibres into the fuel side while the valve is off
• Renew the sealing washers, O-rings or gasket that come with the valve, and never reuse a crushed copper or aluminium washer
• Tighten to the figure in the workshop manual for your engine; these valves screw into fuel housings and heads that strip readily
• Bleed and prime the fuel system as the manual for your engine describes, then run the engine and check the joint for weeping under working pressure
