The Exergy Performance 1-008-003 is a three-way T fitting sized M14x1.5, one of the fuel-system fittings in Exergy's high-pressure line. It is a plumbing part rather than a bolt-on for one truck: a tee joins three lines at one point. You buy it when you are building or changing fuel plumbing and need a tee that matches an M14x1.5 system.
Fitment
This fitting has no single-truck fitment, and our listing carries no engine tag for it. Exergy's own catalog files it under a wide range of Duramax, Cummins and Power Stroke applications, which tells you it is a general fitting rather than a part for one truck.
What decides whether it works for you is the thread. This tee is M14x1.5, so it has to match the M14x1.5 lines and fittings in your plumbing. If you are not sure what thread your system uses, call us before you order and we will help you sort it out.
Why this part
A tee splits one flow path into two, or brings two into one. In fuel plumbing, that is how you tie an added line into an existing one or feed two points from a single source. If the tee goes on the high-pressure side, it has to hold rail pressure and match its thread exactly, and that is the side of the system Exergy builds for.
Exergy's line also includes fuel rails, rail plug kits, CP3 supply fittings and seal kits, so you can source the high-pressure side of a fuel job from one maker.
What you get

Exergy's page does not list lines, nuts or seals with the tee, so plan the rest of the plumbing separately.
