3801857 Injector Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injector weighing 0.601 kg and listed for twelve D4 applications - the D4-180I-B, D4-210A-A and -B, D4-210I-A and -B, D4-225A-B, D4-225I-B, D4-260A-A and -B, D4-260D-B and D4-260I-A and -B. Its published weight is identical to that of 3801858 and within two grams of 3801859, so weight separates none of the three: this one is the narrower D4-only listing, 3801858 spans twenty-seven D4 and D6 F-series applications, and 3801859 has no fitment recorded against it at all. Volvo Penta rebuilds these to the current bill of material with new genuine wear parts and tests every unit before despatch. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn injector is returned.
