3801627 Injector Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injector for the low rating, weighing 0.517 kg and listed for 7 applications across the TAD series. The reman catalogue puts it against the TAD550VE and TAD551VE within the TAD550VE to TAD552VE group, and against the whole TAD540VE to TAD542VE group. Rating and engine designation are the only things separating it from injector 3801661, which the catalogue lists for the TAD552VE and which carries the identical published weight and fitment count. This unit is supplied on an exchange basis: core deposit 3804627 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
