i have two threaded holes right below my iac. does anyone know whats supposed to be there?

 

I'm no expert and new to TPI but I think you have two possibilities; Two #8 (metric) holes, one on top of the other, would be for the fuel line mount. Two larger holes, one on top of the other, would be for the IAT fitting (water temp.) and one would be for the fan temp. switch depending on the year of the car. Also, one of those larger holes could be used for the heater hose outlet.

 

well i know it isnt the fuel line or for a temp switch.

 

Well you never siad exactly where the two holes were and I assumed you meant the ones in the lower intake directly below the IAC (housing). Anyway I mispoke earlier on the two #8 holes ...I think they are #6. Exactly where are the holes?

 

directly under iac. they are vertical bout 2in. apart.

 

Are they in the lower Intake...left of the water outlet?
What is the diameter of the holes?

 

Mount for Corvette fuel rails that come in on pass side

 

well then sch151 i stand corrected.i will just put bolts in them and forget about it. ty vetteoz.
