# 3803917 Unit Injector Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured unit injector for D12-715, D12-775 and D12-800 engines with Delphi injectors, weighing 1.220 kg and listed for five applications in the D series. The engine designations and the Delphi make are the deciding details - 3803637 at 1.211 kg and 3803638 at 1.197 kg are within 24 grams of it and carry no designation - so match the engine rating and the injector make before ordering. This unit is supplied on an exchange basis: core deposit 3806917 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
