What is difference between rotary injection pump and inline injection pump?
An inline pump has multiple high-pressure pumps; one for each cylinder. This one has six pumps, one under each outlet port. A distributor pump has ONE high-pressure pump and uses a rotary valve to distribute high-pressure fuel to each cylinder.
