Is it worth doin? Father in law asked me about it, I don't have a clue.

not really, unless your bored and looking for a small Saturday project involving the truck.

If you want to try it just take the stock one off and run a drill through it, as that's all they do.

Sounds like great advice

Canyon be any worse than when I drilled my cross over tubes. But I'm not doin that sh!t to my father in laws truck.

Sounds like great advice

So what is the purpose of the bigger fitting as far as the advantage of it?

If i remember correctly its like 1/8 drill bit for the drivers side. Did mine when the motor was out. Can't really say if it made a difference or not.

On an LLY and later it helps when power is above 500HP, below that, not needed. You only need to drill the hole out to 1/16" to get all your going to get but some believe bigger is better

Sounds pretty dumb. Fuk it.

Once you get the fitting out it takes 2 seconds to drill it but getting to it is the hard part, the time it takes to loosen the belt move the a/c pump and take the fuel line off it doesnt seem worth it. I wish i would have done a back to back dyno run to see if it made any difference if i ever find a stock one maybe ill try it on a rainy day.

Waste of time unless you are racing. My 2002 never had these drilled until we built the new 7.1.
