Can someone tell me what the two sensors are on the top of the intake? The one in the front that looks like it has a vacuum tube running from it. The other is on the top rear of the intake? Both of mine are broken and I need to know what they are.

 

IIRC ( its been a while since ive had a stock intake on,

One is your MAP sensor, and the one with the " vacuum line" is the evap solenoid, it helps send fuel fumes back to the fuel tank.

 

Awesome! I was hoping that was what the rear one was. Thanks!

 

Thats why were here bro!

 

The front one actually sends fuel vapors into the intake from the tank, not the other way around.

Rear one is the manifold air pressure sensor, MAP

 

I have some spare ones laying around if you need to replace them.

 

I know i'm digging up old stuff. but the evap one is really wiggly on my truck. but the bolt seems tight. so?
