# 3801896 Unit Injector Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured injector from the Fuel System group, weighing 0.97 kg and listed for one application in the TAD series. It supersedes part number 3801810, catalogued earlier as a unit injector. Injector 3801898, the exchange unit for positions 1, 3 and 5, is published at 0.964 kg, so these two are within grams of each other - order by number. This unit is supplied on an exchange basis: core deposit 3804896 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
