# 3801859 Injector Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured injector weighing 0.603 kg. No fitment is recorded against this number in our own records, but Volvo Penta's reman catalogue lists it twice as part of a complete engine package: once with long block 3801702, cylinder head 3801890 and turbocharger 3801173, and once with long block 3801704, cylinder head 3801888 and turbocharger 3801138 - which we list for the D4-300 F-series and the D6-400 and D6-435 F-series engines respectively. Its published weight is within two grams of both 3801857 and 3801858, so mass is no help in telling the three apart. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn injector is returned.
