⚙️ Key Features

• Fuel pump from the Fuel System group
• 0.646 kg
• Supersedes 3858261 and covers its 81 applications across DPX, DP, SP and MS series units
• Within 9 grams of pump 23021433, so weight cannot separate them

🔌 Function

Draws fuel from the tank and delivers it at feed pressure to the engine's fuel system, keeping the supply up as demand rises.

⚠️ Common Signs of Failure

• Engine cutting out or losing power as load is applied
• No buzz, or only a weak one, when the ignition is first switched on
• Hard starting after the boat has stood
• Fuel feed pressure below specification when gauged
• Strainer blocked or pump internals worn on strip-down

🛠️ Service Notes

• Check the filters, tank pickup and the voltage at the pump before condemning it - starvation and low voltage both mimic a failed pump
• Pump 23021433 sits within 9 grams of this one, so order strictly by part number
• Renew the sealing washers and o-rings on the fuel connections rather than reusing them
