3801396 Unit Injector | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured unit injector from the Fuel System group, weighing 1.188 kg and listed for 7 applications on TAD-series engines. In the D16 industrial tables it is the injector listed against long blocks 3801515 and 3801687 with cylinder head 3801803 and turbocharger 3801421, and it is also the injector for complete engine 3801968. The reman injectors in this range are separated by grams rather than by anything visible, so the part number and the engine designation are what decide the order. As a Reman component it is stripped to the core, restored to what is technically new condition with wear parts replaced by new genuine parts, built to the current bill of material and tested before despatch. It is supplied on an exchange basis: core deposit 3804396 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
