# 3803724 Injection Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 19.4 kg, recorded against two applications across the TWD and TD series, and superseding injection pump 866206. It is the only pump in this range in the 19 kg band - 3803709 at 18.6 kg and 3803727 at 18.8 kg are the nearest below it - so the weight is a reasonable sanity check, though the superseded number is the safer guide. This unit is supplied on an exchange basis: core deposit 3806724 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
