# 3806732 Injection Pump Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core line for an injection pump, held 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. The unit the deposit is raised against is part number 3803732; that is where the pump itself comes from, and the two go on the order together. The line is listed at 18.144 kg. Nothing goes out against the deposit, so read that as the scale weight of the pump coming back for credit - a one-man lift, so it can go back the way it came. Injection pump core 3806775 is published at the same 18.144 kg and carries the same name, so the figures do not separate the two - 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 3803732
-   Refunded when the old injection pump is returned
-   18.144 kg listed, the return weight to plan freight around
-   Shares its published weight with injection pump core 3806775, 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
-   The engine cutting out under way and picking up again once it has stood
-   Far more fuel going back to the tank on the return than the engine should be spilling
-   The engine down on one bank or one cylinder with no injector, compression or valve fault behind it
-   Hard starting, or long cranking before the engine will fire

## 🛠️ 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 3803732
-   Water and dirt in the fuel are what finish most pumps, so clean the tank and renew the filters at the same time or the exchange unit goes the same way as the old one

-   Refundable core deposit - not a physical part
