The Exergy Performance 1-018-129 is an M14x1.5 union, the fitting that joins two M14x1.5 connections. Exergy files it under its Cummins, Duramax and Powerstroke fittings, with a vehicle list that covers GM, Ram and Ford heavy-duty trucks and vans. You buy it when two M14x1.5 connections in a fuel system need to be joined with a proper fitting.
Fitment
Exergy's vehicle list for this union is broad. It includes:
- Chevrolet Silverado and GMC Sierra 2500HD, 3500 and 3500HD pickups, including 2007 Classic models, and Chevrolet Express and GMC Savana 2500 and 3500 vans, all with the 6.6L Duramax
- Ram 2500 and 3500 with the 5.9L or 6.7L Cummins, and Ram 4000 with the 6.7L Cummins
- Ford F-250 and F-350 Super Duty with 6.0L, 6.4L, 6.7L or 7.3L engines, Ford Excursion with 6.0L or 7.3L engines, and Ford E-350 vans with 6.0L or 7.3L engines
Because it is a thread-size fitting, the threads matter more than the truck. Confirm both connections you are joining are M14x1.5, a 14 mm thread with a 1.5 mm pitch. Verify by VIN or call us if you are not sure.
Why this part
A union is the part you want when two M14x1.5 connections need to meet, whether you are re-routing a line, joining two sections or building a custom setup. Exergy makes this fitting as part of the same high-pressure line it builds rails, pumps and relief valves for, so the joint in your fuel system comes from a common-rail parts maker rather than a general hardware bin.

Frequently asked questions
Which trucks is this union listed for?
Exergy lists it for 6.6L Duramax GM pickups and vans, 5.9L and 6.7L Cummins Rams, and Ford Super Duty, Excursion and E-350 models. Since it fits by thread, confirm both connections are M14x1.5 first.
What if one side of my joint is M18x1.5?
Then this union is not the part. Exergy's M18x1.5 rail end to M14x1.5 adapts an M18x1.5 rail connection to M14x1.5. Call us and we will help you sort out which piece your setup needs.
Does it come with lines?
Exergy's listing names the union only and mentions no lines, so plan on supplying your own.
