Abstract: Intake manifold-cylinder head connectors and methods of assembling the same are disclosed. A distal jumper tube includes a distal jumper tube conduit with an upstream end having a first exterior engagement feature and a downstream end. A proximal jumper tube includes a proximal jumper tube conduit with an upstream end and a downstream end having a second exterior engagement feature. A middle jumper tube includes a middle jumper tube conduit with an upstream end having a third exterior engagement feature, and a downstream end having a fourth engagement feature. The first exterior engagement feature is removably coupled to the fourth exterior engagement feature, and the second exterior engagement feature is removably engaged to the third exterior engagement feature. The proximal jumper tube is in fluid receiving communication with an intake manifold conduit, and the distal jumper tube is in fluid providing communication with a cylinder head aperture.

Abstract: Disclosed embodiments include a pump assembly comprising a pump including a rotating drive shaft having a tapered end portion, a first alignment structure on the drive shaft, and a hub adapter including a first mounting portion comprising a tapered opening and a second mounting portion extending from the first mounting portion and configured to receive a drive member. The tapered opening is configured to be inserted onto and engaged with the tapered end portion of the drive shaft. A second alignment structure is located on the hub adapter, and the first alignment structure and the second alignment structure cooperate to enable a predetermined registration of the hub adapter on the drive shaft. A fastener structure secures the hub adapter to the drive shaft.
