After driving my truck and I park it. I'll come back say at least 5 minutes later, Ill get a nice smell of gas. Not too strong but you can tell its gas. Anyways, I looked all under, followed the fuel lines and theres no leak there. You can smell it inside the cab so it must be comin from under the hood. Could it be a bad injector maybe? Just wondering if anybod else has had this problem and if its a big deal or not.

if there really was a fuel leak, wouldnt the SES light come on when it did a pressure test?.....cause mine hasnt lit up yet and ive been having this gas smell for while
I had the same problem. Finally found an injector had a hairline crack just above the hold down clamp. It was the injector directly under the TB so it was impossible to see. At first I thought it was a bad o-ring but that was a wasted fix. The second time around I spotted the crack.

i don't have any gasoline spilling anywhere, and the strongest smell is on the mid driver's side. I thought maybe it was the gas cap, its not that.
so you say check the charcoal canister connections? what is that one huge 1" line that comes to a unit that's the size of a pack of a camera? i don't think that's the evap canister, i think the evap sits right above the differential, right?

mine did the same thing it was an injector..look at them for wet lookin dirt on top of them, and if u replace them i would get gm injectors, theyre a little more expensive, but i had bad experiences with 3 aftermarket, and i wouldnt get the oring either cuz i did that on 2 of them and they still leaked

fixed up now
I have had 2 fuel leaks on my s10. The first was a leaky fuel injector o-ring. Second was the fuel line 'directly under" the drivers seat. The metal line had rubbed back and forth under the floor, very, very hard to find. the leak was no bigger than a pin hole. and it was on top of the fuel line making it even harder to find. Small enough to leak out a minute amount of fuel under pressure, but not small enough to drip. I repaired it by slipping a piece of rubber fuel hose "slit" across the tip over the line and placing a hose clamp around it, thereby not only closing up the hole, but also keeping the fuel line from chaffing any more on the floorboard of the truck. Directly UNDER the driver's seat, extremely hard to find.
A gas leak is a big deal. It will not go away.
1) Find it
2) Fix it
OR
3) Buy a large fire extinguster and carry it everywhere with you.
