⚙️ Key Features

• 0.057 kg
• 25 D series engine applications

🔌 Function

Allows fuel to pass in one direction only, holding the line full so the system stays primed when the engine is stopped.

⚠️ Common Signs of Failure

• Long cranking to start after the engine has stood, then normal restarts while hot
• Loss of prime, with the lines found empty at the filter
• Air bubbles visible in the fuel line
• Rough or lumpy running for the first few seconds until the air is purged
• Fuel weeping around the valve body or its connections

🛠️ Service Notes

• Check the filter seals and line unions for an air leak before condemning the valve, since either gives the same symptoms
• Note the flow direction on removal and prime the system after fitting
