Abstract: An accumulator clamp for an accumulator assembly in an engine assembly is disclosed. The accumulator assembly further includes an accumulator body and a fuel line adapter connected thereto, and the accumulator assembly is mountable into a cylinder head accumulator bore of a cylinder head. The accumulator clamp includes a clamp body having a clamp accumulator bore receiving an end of the accumulator body, and a bolt bore on either side of the clamp accumulator bore for receiving threaded portions of accumulator mounting bolts that secure the accumulator assembly to the cylinder head. The bolt bores include bolt slots through the walls of the accumulator body so that the threaded portions of the accumulator mounting bolts are insertable into and removable from the bolt bores through the bolt slots to allow installation and removal of the accumulator assembly without disassembling components of the engine assembly around the cylinder head.

Abstract: A resilient seal member disposed in an alignment groove of an accumulator body centers the accumulator body in an oversized accumulator bore of a cylinder head to prevent assembly damage. The seal member can compress to allow the accumulator body to move off center within the accumulator bore so that an end may be received by and form a seal with a port of a fuel injector. The alignment groove and the seal member are configured so that cooling fluid can flow past the seal member when the accumulator body is installed. In one implementation, the accumulator body includes at least one fluid flow channel at the alignment groove having a depth greater than the alignment groove so fluid can flow through the channel to pass the seal member.
