3804863 Fuel Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Nothing is despatched against this number. It is the refundable core charge that goes on the invoice alongside an exchange fuel pump, standing in for the worn fuel pump until that unit comes back. Volvo Penta numbers a core deposit 3000 above the unit it belongs to, which puts this one against 3801863, listed in our catalogue as Fuel Pump Exch. Near-identical fuel pump deposits sit alongside it, among them 3804861 and 3804862, and nothing in our records separates one from another, so order by the number of the fuel pump being exchanged. The sum is released back when the used unit arrives with us.

⚙️ Key Features

• Refundable core charge, not a part that ships
• Pairs with 3801863, listed as Fuel Pump Exch
• Raised against the old fuel pump on an exchange purchase
• Near-identical siblings include 3804861 and 3804862
• Credited when the old fuel pump is returned

🔌 Function

Carries the refundable core charge on a fuel pump exchange. The charge itself buys nothing; the pump it stands against draws fuel from the tank and delivers it to the injection system at the pressure and timing the engine needs.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the fuel pump being exchanged
• Hard starting, or long cranking before the engine fires
• Power loss and heavy smoke once the engine is put under load
• Diesel weeping from the pump body, its shaft seal or its unions
• Hunting, surging or an idle that will not settle

🛠️ Service Notes

• Ordering this line on its own supplies no fuel pump. It is the deposit that rides alongside the exchange unit, so the fuel pump itself has to be ordered as a separate line.
• The charge is refunded when the old fuel pump comes back to us complete and rebuildable; a unit that has been stripped for parts, broken up or damaged in transit is normally refused for credit.
• Send the old pump back with its unions blanked and the drive coupling or gear still fitted, and check the lift pump, filters and tank pickup before condemning it.

📦 Condition

• Refundable core deposit - not a physical part
