# 3806711 Injection Pump Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for an injection pump, from 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 3803711, which is the number to quote for the component itself. The line is published with a weight of 24.04 kg, which is a guide to what the old injection pump weighs on its way back rather than to anything that ships out against the deposit. That figure converts to exactly 53 lb, so read it as a shipping-scale round number rather than a measured mass. It is one of 30 injection pump cores running through this block and 15 of them carry no published weight at all, so weight will not tell the set apart - order the number that matches the injection pump actually coming off.

## ⚙️ Key Features

-   Belongs with the exchange unit, part number 3803711
-   Refunded when the old injection pump is returned

-   Fuel System group

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the pump itself raises fuel to injection pressure and delivers a metered charge to each injector in firing order and at the right moment.

## ⚠️ 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
-   Scored, seized or metal-contaminated internals found when the pump is stripped or bench tested
-   Hard starting, or the engine cutting out and refusing to restart while hot
-   Power down across the range, with smoke at the exhaust and fuel consumption up
-   A hunting or erratic idle that will not settle

## 🛠️ 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 3803711
-   Prove the lift pump, filters and fuel supply before condemning the pump, and allow for the exchange unit needing timing to the engine on fitting

## 📦 Condition
