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.
