3803716 Injection Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injection pump for electric speed control, in the standard (Std) setting, weighing 25.2 kg and listed for three applications across the TWD, TD and TAD series. It supersedes injection pump 865559. Electric speed control is the deciding detail here - it is the only pump in this range carrying that note apart from the electronic pump 3803752 - so confirm how the engine's speed is controlled before ordering. This unit is supplied on an exchange basis: core deposit 3806716 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
