# 3803709 Injection Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 18.6 kg, recorded against three applications across the TWD, TD and TAD series, and superseding injection pump 864847. The reman catalogue lists this number against TWD1010G at the 212 kW rating. Its sibling 3803708 weighs 16.93 kg, supersedes 864845 and shares the same three applications across the same three families, so name and fitment separate nothing - check which of 864847 or 864845 the engine's own list shows before ordering. Supplied on exchange: core deposit 3806709 is charged alongside it and refunded once the old pump is returned.
