# 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
-   Maintains low-pressure fuel-system backpressure

## 🔌 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
