3806775 Injection Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Injection pump core deposit, from the Fuel System group. 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. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3803775, which is the number to quote for the pump itself. 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 3806732 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 3803775
• 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 3806732, 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
• Fuel starvation symptoms that stay after the filters, lift pump and lines have been proved good
• Stiff or binding drive as the engine is turned over, with the pump loading the timing gear
• Far more fuel going back to the tank on the return than the engine should be spilling

🛠️ 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 3803775
• 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

📦 Condition

• Refundable core deposit - not a physical part
