The Exergy Performance 1-018-133 is an M18x1.5 rail plug. It closes off an M18x1.5 port on a common-rail fuel rail. Exergy does not publish a vehicle list for it, so you match it to your rail by thread size, not by truck or year. If the port is M18x1.5 and it is coming out of service, this is the plug.
Fitment
This plug is listed in Exergy's general fittings with no engine or model-year list. The port it goes in has to be M18x1.5, an 18 mm thread with a 1.5 mm pitch. Exergy also sells engine-specific rail plugs, including a fuel rail plug kit listed for the LBZ and LMM Duramax and a flush-mount M18x1.5 plug listed for the 2011-2016 6.6L Duramax. If your truck is one of those, call us before ordering so you end up with the right plug. Otherwise, check the port thread or send us your VIN.
Why this part
If a port on your rail is coming out of service, it needs a plug that matches its thread. This is Exergy's plug for an M18x1.5 port, the larger-thread counterpart to its M14x1.5 rail cap. Exergy builds rails, pumps, rail pressure sensors and relief valves for Cummins, Duramax and Powerstroke diesels, and this plug comes out of that same high-pressure line.

Frequently asked questions
Does this plug fit my truck?
It fits an M18x1.5 port. Exergy does not list specific trucks for it, so check the thread on the port you are closing, or call us with your VIN.
Is this the same as Exergy's flush-mount rail plug?
No. The flush-mount M18x1.5 plug is a separate Exergy part listed for the 2011-2016 6.6L Duramax, and it needs a triple-square bit. This is the general M18x1.5 rail plug.
Should I use this or the M14x1.5 rail cap?
Go by the port. An M18x1.5 port takes this plug, and an M14x1.5 port takes the rail cap. If you are not sure which you have, we can help you check.
