The Exergy Performance 1-018-043 is an M14x1.5 plug and nut sold as a rail cap. It closes off an M14x1.5 port on a common-rail fuel system when nothing is connected to that port. Exergy does not publish a vehicle list for it, so you match it to your truck by thread size, not by year or model.
Fitment
Exergy lists this cap under its general fittings and does not tie it to a specific engine, truck or model year. Fitment comes down to the port you are capping. It has to be an M14x1.5 thread, which means a 14 mm thread with a 1.5 mm pitch. Check the port, or the line nut you are taking off it, before you order. If you are not sure what your rail uses, call us with your VIN, tell us which port you are working on, and we will help you confirm it.
Why this part
When a high-pressure line comes off a rail and is not going back on, the open port still has to be closed. This is the fitting for that: a plug and nut from a company that builds high-pressure common-rail parts, sold by Exergy specifically as a rail cap. A typical reason to need one is a fuel system that has been plumbed differently from stock and leaves an M14x1.5 port with nothing on it.

Frequently asked questions
Will this rail cap fit my truck?
Exergy does not publish a vehicle list for it. It fits an M14x1.5 port, so confirm the thread on the port you are closing off. Send us your VIN, tell us which port it is, and we will help you check.
How is this different from the M18x1.5 rail plug?
Thread size. This cap is for an M14x1.5 port. Exergy's M18x1.5 rail plug is for the larger M18x1.5 port. Order the one that matches the port on your rail.
Is there a torque spec for it?
Exergy's listing does not give one. Call the shop before you install it and we will go over it with you.
