Delphi Fuel Injector P/N:EX631042
Delphi FJ10494 fuel injector for the 2001-2007 Chevrolet C6500 Kodiak V8 8.1L and other vehicles delivers a metered spray of fuel to the engine. Delphi injectors are tested using OE methodologies.
A leaking, plugged or worn injector can show up as a rough idle, hesitation or hard cold starts. Before you replace an injector, rule out fuel pressure, ignition and wiring faults first, because they can also give rough idle or hesitation.
The same injector is a direct-fit replacement for the 2001-2007 Chevrolet C7500 Kodiak V8 8.1L and the 2001-2007 GMC C6500 Topkick V8 8.1L. A full set for the 2001-2007 Chevrolet C6500 Kodiak V8 8.1L takes eight, and this listing is one injector.

Does the Delphi FJ10494 fit the 2001-2007 GMC C6500 Topkick V8 8.1L?
Yes. Delphi FJ10494 fits the 2001-2007 GMC C6500 Topkick V8 8.1L and many other vehicles. If your truck is not named here, look it up in the "Vehicles it fits" section.
What comes with this Delphi fuel injector?
The package is one fuel injector and one instruction sheet.
Does this injector have internal seal rings?
No. Delphi FJ10494 has no internal seal rings, which minimizes leakage, and its recessed fuel exit minimizes possible plugging.
What are the signs of a leaking or clogged fuel injector like the Delphi FJ10494?
With the engine off and cool, look for fuel wetness around the injector. Rough idle or hesitation can be signs too, and a shop can test the spray and flow.
How does this injector deal with vapor lock?
It pulls manifold heat away from the fuel rail, keeping the fuel thermally isolated from the engine. That helps prevent hesitation caused by vapor lock.
