# 3801441 Unit Injector | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured unit injector for the D9 range, weighing 1.222 kg and listed for seven applications across the D9A2A to D9A2M engines. Its nearest neighbour here is 3801433 at 1.211 kg, the D11 unit injector - eleven grams apart, which is no basis for an order, so match the engine series. Volvo Penta reman components are rebuilt to the current bill of material, so design changes made since your engine was built are carried in, with wear parts replaced by new genuine parts and every unit tested before it is painted and despatched. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn unit is returned.
