Abstract: A leak detection tool for a double walled fuel rail system is provided. The tool includes a body having a first end and a second end distal with respect to the first end. The tool includes a first passage extending from the first end at least partially towards the second end. The tool includes a second passage axially aligned with and extending from the first passage towards the second end. The tool includes a seat defined at an intersection of the first passage and the second passage. The tool also includes a sealing element provided in association with the seat within the second passage. The tool further includes a spring element provided within the second passage and in contact with the sealing element. The first end is configured to block fluid communication between outer passages of adjacent portions of the double walled fuel rail system.

Abstract: An exhaust system for a power system contained in an engine compartment. The exhaust system includes a mount for two or more exhaust treatment devices and an enclosure surrounding the two or more exhaust treatment devices. The enclosure defines a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system. At least one electronic or fluid device is coupled to the enclosure or mount and located on an exterior of the enclosure.

Abstract: The present application includes apparatuses and service methods including a valve cover assembly for an internal combustion engine. The valve cover assembly optionally including: a valve cover; a base extension coupled to the valve cover and having a recess that receives at least a portion of a rocker arm therein; and a grommet coupled to at least the base extension, the grommet having one or more openings for passage of one or more fuel tubes into the recess to deliver one or more fuels to a fuel injector. The at least one of the valve cover and the base extension is removable from the internal combustion engine without disturbing the one or more fuel tubes to provide access to the rocker arm for performing a valve lash adjustment thereon.
