Ok so after doing some research on here, I couldnt find anything near my problem.. I started smelling gas from inside my Blazer while its running. But you can ONLY smell it from the inside and while its running. Its not really strong but you can smell it still. The rig is not throwing me any codes or lights. Still runs good and all. Been like this for a couple of days now. Ive tried to look but cant find any visible leaks or anything. Anyone have any idea on what it could be or know what it is?

 

look at the schrader valve on the fuel rail. Mine was loose once and the smell was bad inside the cab.

 

Hmm never thought about that!

 

Yeah i get that smell sometimes also. I would also take your intake boot off and open up the throttle (not running) and smell inside there for raw gas. could possibly have a small leak in the spider.

 

Ok so either I got used to the smell or it went away cause I havent noticed it in the last few days. Idk tho. I looked at everything you guys mentioned and i didnt see anything wrong with it at all.

 

Check the vac line to the vacuum reservoir the hood. When mine is unplugged, I smell gas inside the truck.
