I tried asking this on LS1tech but I guess I don't know the secret password over there to get any responses. I need to get my IAT sensor and a vacuum line hooked up into the air intake I am piecing together on my LS.
I'm eyeballing this to use for both:

I'm hesitant because it says its good up to 3" diameter hose. I am running a 4" (feeding a 102 intake). Has anybody used this on anything larger than 3"? I'm guessing they limit it to 3" dia for sealing issues but wonder how bad it would really be on a 4" silicone section.
Does anyone know of anything else that is available? I guess my other option is to have a couple NPT bungs welded onto an aluminum straight section but that would have to be plan B as I would not be able to weld that myself.
thanks...
