Dorman - OE Solutions Fuel Injector Line P/N:904-966
Dorman 904-122 right fuel injector line for the 2004-2010 Chevrolet Silverado 2500 HD V8 6.6L and other vehicles is a diesel return line that carries excess fuel away from the injector. It is a direct replacement for the original line on the vehicles it fits.
A wet or cracked line, fuel seeping at a fitting or a diesel smell near the injectors can mean a return line needs replacing, but a leak somewhere else in the fuel system can look just the same. Before you buy, look over the line and its fittings with the engine off and cool, and leave any test that needs the engine running or a fuel line opened to a shop. This listing is one right-side line; a 2007-2010 Chevrolet Silverado 3500 HD V8 6.6L takes one on that side, and the other side is ordered separately.
The 2004-2010 Chevrolet Silverado 2500 HD V8 6.6L, the 2007-2010 Chevrolet Silverado 3500 HD V8 6.6L and the 2004-2010 GMC Sierra 2500 HD V8 6.6L all take this fuel injector line, and so do more vehicles. Open the "Vehicles it fits" section to check your exact model and engine.

The package is one fuel injector line for the right return side. The other side is a separate part.
What are the length and diameters of the Dorman 904-122 fuel injector line?
Dorman 904-122 is 10 inches long with a 0.117 in inside diameter and a 0.313 in outside diameter. The line is rubber with plastic fittings.
How can I tell if a diesel return line is leaking?
With the engine off and cool, look for a wet, cracked or fuel-stained line or fitting. A diesel smell near the injectors can be another sign, and a shop can test anything that needs the engine running.
Can I reuse the old injector line and just swap the seal?
No. Each fuel injector line has a one-time-use crushable seal, so the entire line is replaced to get an optimal seal.
