3803933 Unit Injector Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured unit injector weighing 0.302 kg, from the Fuel System group, with no fitment list published against it. It is much the lightest item named as a unit injector in this range - the others run from 0.594 kg to 1.99 kg - and its weight instead matches the plain injectors 3803935 at 0.308 kg and 3803602 at 0.315 kg, so check the number carefully against the engine's own list before ordering. This unit is supplied on an exchange basis: core deposit 3806933 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
