Eight fuel injectors.
The 2004 Tahoe offered several V8 engine options, and all of them use a port fuel-injection system with one injector per cylinder. Since these are eight-cylinder engines, the total comes to eight injectors.
Engine options for the 2004 Tahoe
The Tahoe lineup in 2004 included multiple V8 configurations depending on trim and drivetrain. The main options were:
- 4.8L V8 (Vortec 4800)
- 5.3L V8 (Vortec 5300)
- 6.0L V8 (Vortec 6000) — typically found in heavier-duty 2500HD/Tahoe variants
All of these eight-cylinder engines share the same basic fuel-injection approach, which is eight injectors total—one for each cylinder.
Fuel-injection configuration
In the Tahoe’s V8 engines, fuel is delivered to each cylinder via port injectors located at the intake ports. This results in a total of eight injectors for the eight-cylinder configurations commonly found in 2004 Tahoe models.
Conclusion: Regardless of the V8 option installed, the 2004 Chevy Tahoe uses eight fuel injectors—one per cylinder.
