I was messing around under the hood this morning when I noticed somthing that looked interesting. Its a black cannister that sits on the driver side, just beside the Radiator. I have no idea what its for and got a little curious. I have never seen anything like it before. It has 2 lines. one runs under the motor and no idea where it leads to after that. The other heads to the throttle body. Any ideas?

Truck is an 89 blazer 350 TBI

I am attaching pictures of it, hopefully it get it right.

Thanks

 

Evap canister. Controls evaporative emissions from the fuel tank.

 

I'd say it's the charcoal evaporative canister. Part of the emission system.

**Damn, Kyle, I still say you type too fast**

 

I do not think there is such a thing as typing too fast. Too slow on the other hand! LOL
