3801912 Injector Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injector from the Fuel System group, weighing 0.498 kg and listed for 3 applications in the TAD series. It sits with the other half-kilo injectors here - 3801855 at 0.506 kg and 3801854 at 0.510 kg - so weight will not separate them and the application list decides the order. This unit is supplied on an exchange basis: core deposit 3804912 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
