VE pump or P-pump?
Most people come here for the injection pump, so first work out which one you have: the VE pump or the P7100 P-pump. Injector sets, nozzle sets, front gear cases and front cover gaskets are listed separately for each. Not sure? Send us the engine number or a photo of the pump and we will confirm.
Cylinder heads and head gaskets
We list a new 4BT cylinder head, MAHLE head gaskets and upper gasket sets in standard, +010 and +020 thickness, and ARP Pro Series head studs. If the head or block has been machined, tell us how much came off and we will confirm the thickness.
