# 20528999 Ball | Genuine Volvo Penta Part

## 🔧 Product Description

It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta TAD11/TAD13/TAD16 fuel systems application. Technical identification: Precision ball in the fuel-filter hand-pump/control-valve assembly. In service, it acts as the closing element in the fuel-filter hand-pump or check-valve circuit, allowing flow in the intended direction and preventing drain-back. Selection must be confirmed by OEM part number 20528999, the exact model/product number, serial number and installed assembly configuration.

-   Genuine Volvo Penta OEM ball
-   OEM part number 20528999

## 🔌 Function

Acts as the closing element in the fuel-filter hand-pump or check-valve circuit, allowing flow in the intended direction and preventing drain-back. Flush the connected circuit, confirm port orientation and calibration, renew seals and verify pressure/flow operation through a complete operating cycle.

## ⚠️ Common Signs of Failure

-   Fuel drains back after shutdown, causing extended cranking
-   Hand primer will not build or retain pressure
-   Air remains trapped in the fuel-filter circuit after bleeding
-   Uneven fuel supply or starvation under load
-   Ball or seat contamination, pitting or corrosion prevents sealing

## 🛠️ Service Notes

-   Renew the ball whenever the valve or seat it works in is dismantled — a ball that has bedded into one seat will not seal in another
-   Work spotlessly clean and handle it with clean hands or a magnet; grit carried in on a ball goes straight into the fuel or hydraulic circuit
-   Inspect the seat for pitting, a wear ring or damage before fitting, because a marked seat will leak with any new ball
-   Seat the ball with a soft drift and light taps only where the workshop manual for your engine actually calls for it to be seated, and never drive it in harder than the manual says
-   Check the spring, guide or retainer that works with the ball is present, undamaged and fitted in the right order, then check the valve holds before returning the system to service
