3803700 Injection Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 16 kg and recorded against 59 applications across the TD, TID, AQ, BB, B and MD series - the broadest fitment of any pump in this range. The reman catalogue lists this number against TD100HP. It supersedes injection pump 863451. The six-family spread is what makes it distinctive; by weight the nearest to it is 3803708 at 16.93 kg. Reman components are rebuilt to a bill of material carrying all design changes, tested and painted, so they meet the current technical specification.
