# 3806754 Injection Pump Core | Genuine Volvo Penta Part

## 🔧 Product Description

Refundable core deposit raised against an injection pump, listed under Fuel System. It carries the charge that goes on when the exchange pump is supplied and comes off again when the old pump is handed back. No hardware moves against the line itself, so ordering it alone brings nothing to the boat. Core numbers in this series run three thousand above the unit they belong to, so the pump this deposit stands against is part number 3803754. Every line in this run carries the same injection pump core name with no fitment against it, so the part number is the only thing that ties a deposit to a particular pump - take it from the unit being exchanged.

## ⚙️ Key Features

-   Core deposit line, not an injection pump you can fit
-   Belongs with the exchange unit, part number 3803754
-   Refunded when the old injection pump is returned
-   No engine application published against the line, so order by part number
-   Fuel System group

## 🔌 Function

The line's job is to hold the refundable deposit until the old unit is back; the pump it stands against raises fuel to injection pressure and doses each cylinder in turn, setting how much fuel the engine gets and when it gets it.

## ⚠️ 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
-   Loss of power, with the engine unable to pull up to its rated revolutions
-   The engine cutting out under way and picking up again once it has stood
-   Black smoke under load, or white smoke that hangs about long after start-up
-   Diesel weeping from the pump body, the top cover or the drive-end seal

## 🛠️ Service Notes

-   The charge is refunded when the worn injection pump is returned, so keep the old pump 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 3803754
-   Cap the pump's ports and the engine's fuel connections the moment the old unit comes off - dirt getting in is what undoes an exchange
