15' 6.2 injector tic

[Steeks]

I'm sure it's normal but seem loud. Anybody do anything to quiet them up. Don't seem to matter if it's 90 or 92 octane don't seem to help. Any advice or ideas, only have 7k

Before I bought my truck, I researched that noise pretty thoroughly. although mines a 5.3, it's completely harmless and normal!

My 6.2 is the same -they say it is because of the DI and high pressures.

I have a 15 Corvette and it is actually louder -almost sounds like solid lifters at times LOL

I've looked into this a lot, it's the mechanical fuel pump driven by the camshaft. It's under the intake manifold
