3803727 Injection Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 18.8 kg and listed for one application in the TWD family. It supersedes injection pump 866365. Our fitment record puts it on TWD610V while the reman catalogue lists the number against TWD610P, so read the designation off the engine plate before ordering. It sits close to 3803709 at 18.6 kg and 3803743 at 18.5 kg, so weight will not distinguish them - the single TWD application and the superseded number 866365 are what place this pump. Supplied on exchange: core deposit 3806727 is charged alongside it and refunded once the old pump is returned.
