# 3806867 Injection Pump Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for an injection pump, in the Fuel System group. It is the refundable charge raised against the old injection pump when the exchange unit is bought, and it comes back once the worn injection pump is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3803867, which is the number to quote for the component itself. Nothing published against this line separates it from the other injection pump cores running through this run, so order the number that matches the pump actually coming off.

## ⚙️ Key Features

-   Core deposit line, not an injection pump you can fit
-   Belongs with the exchange unit, part number 3803867
-   Refunded when the old injection pump is returned
-   Not separable from the other injection pump cores here, so order by part number
-   Fuel System group

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the pump itself meters the fuel, raises it to injection pressure and delivers the right quantity to each cylinder at the right moment, which is what governs how the engine starts, idles and pulls.

## ⚠️ Common Signs of Failure

-   This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injection pump being exchanged
-   Long cranking or a refusal to start, worst from cold
-   Power and top revs down, with black smoke building under load
-   Hunting or surging at idle, or a knock that comes and goes as the engine warms
-   Diesel weeping from the pump body, its shaft seal or the delivery unions

## 🛠️ Service Notes

-   The charge is refunded when the worn injection pump is returned, so keep the old unit and send it back rather than scrapping it
-   Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3803867
-   Find out what killed the old pump before the exchange unit goes on - water or dirt carried through from the tank will take the replacement out the same way, so renew the filters and prove the fuel clean first
