3806745 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 3803745; that is where the pump itself comes from, and the two go on the order together. The line is listed at 23.133 kg. Nothing goes out against the deposit, so read that as the scale weight of the pump coming back for credit - a two-man lift, or one man and a hoist. The lines in this run are not separated by any published engine application, so match the number to the pump coming off rather than trying to identify it by description.

⚙️ Key Features

• Core deposit line, not an injection pump you can fit
• Belongs with the exchange unit, part number 3803745
• Refunded when the old injection pump is returned
• 23.133 kg listed, the return weight to plan freight around
• 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
• Hard starting, or long cranking before the engine will fire
• Smoke and rough running that a full service and a tank of clean fuel do not improve
• The engine running on after the stop control has been pulled
• Loss of power, with the engine unable to pull up to its rated revolutions

🛠️ 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 3803745
• 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

📦 Condition

• Refundable core deposit - not a physical part
