3804396 Unit Injector Core | Genuine Volvo Penta Part

🔧 Product Description

This is the unit injector core deposit from the Fuel System group. It is the refundable charge on the unit injector you return when buying the exchange unit, and it ships nothing on its own. It pairs with part 3801396, and that is the number that supplies the unit injector itself.

⚙️ Key Features

• A deposit line, not a shippable part
• Refunded on return of the old unit injector
• Pairs with part 3801396

🔌 Function

Carries the refundable charge on an exchange unit injector, and is credited back when the worn unit injector comes in.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the unit injector being exchanged
• Hard starting from cold and smoke that thins out as the engine warms
• A fault logged against a single injector solenoid or its control circuit
• Plunger and barrel worn, so the unit no longer builds the injection pressure it should
• Nozzle tip coked or eroded and the spray pattern broken up

🛠️ Service Notes

• The charge on this line is refunded on return of the old unit injector.
• Ordering this number on its own supplies no part - the unit injector comes from its paired line, part 3801396.

📦 Condition

• Refundable core deposit - not a physical part
