Hey guys new member here, my car was sounding like it had a small vacuum problem maybe in the lines so i replaced all of the vacuum lines around the throttle body and the egr valve but when i got to replacing them with the line i bought at checker auto i noticed that the ones on the throttle body look to be a different size.

They actually look like the whole is a bigger diameter and i ended up using a smaller size on them,

my question is will this negatively effect my performance in any way???
Does anyone have the exact sizing of the vacuum lines around the throttle body and egr valve???

thanks in advance guys

 

no advice guys? i would really appreciate it if someone could point me in the right direction. do i need a catchy thread title or something?

 

i don't think it would effect overall engine performance, but it might collapse the line sooner than with the right size line. Don't know the exact size srry.
