3804330 Injector Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit line for an injector, held in the Fuel System group. The line exists to hold the refundable charge on the old injector being handed back against an exchange unit; no hardware moves against it. Its pair is part 3801330, which is where the injector comes from. The row carries a recorded weight of 0.907 kg. Injector deposit 3804329 carries the same name, the same group and the same recorded weight of 0.907 kg, so nothing on the two rows separates them - go by the part number and by the unit each one is paired to.

⚙️ Key Features

• A deposit line, not a shippable part
• Refunded on return of the old injector
• Pairs with part 3801330
• 0.907 kg recorded
• Not separable from 3804329 on the record - order by number

🔌 Function

Holds the refundable core charge against an exchange injector and releases it once the old injector is returned.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injector being exchanged
• Rough idle with a misfire that can be traced to one cylinder
• Hard starting, black or white smoke, and fuel consumption creeping up
• A knock or rattle from one cylinder that changes with load
• Back-leakage well above what the pipe should return, so the engine runs down on pressure

🛠️ Service Notes

• The charge on this line is refunded on return of the old injector.
• Ordering this number on its own supplies no part - the injector comes from its paired line, part 3801330.
• Check which unit the engine actually takes before ordering - 3804329 and 3804330 cannot be told apart from their records alone.

📦 Condition

• Refundable core deposit - not a physical part
