I just got my driver side header in, and I went to screw in my AIR fitting.. and it's too small! (my old fitting is too small, the diameter on the jet-hot injection tube is too big)

Did they send the wrong thing? Am I doing something wrong?

Thanks!

 

Later Z28s used a smaller AIR tube. You got the early style header (22mm instead of 18mm)

 

What should I do? Can I just take it to a Home Depot or somewhere and just have them find a 22mm peice?

 

They wouldnt stock it. If you just want to plug up the hole, you'll need a 22mm drain plug, M22x1.5 is the thread size.

 

I know they wouldn't stock the exact peice that I need.. but wouldn't they have some sort of 18mm - 22mm adaptor? I want to avoid just sticking a plug in.

 

Not likely that any such adapter is made
