# 3803950 Injection Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 0.982 kg and listed for three applications across the TD and TAD series - the reman catalogue lists this number against TAD420VE, TD420VE and TAD620VE. It is the only small pump in this group listed against TD and TAD rather than the D series, which is what places it: by weight it sits among 3803899 at 0.930 kg, 3803967 at 1.025 kg and 3803910 at 1.059 kg, all within 80 grams. Reman components are rebuilt to the current bill of material with new genuine parts in place of anything worn, then tested and painted. Supplied on exchange: core deposit 3806950 is charged alongside it and refunded once the old pump is returned.
