So, my 2010 has been throwing the "small evap leak" code as well as illuminating "GASCAP" in the odometer section of my Jeep. I can tell you my gascap is on and tightened, however I do smell a small amount of fuel vapor from the passenger rear side of my Jeep after I park. Has anyone else had this issue, or know of an solution. I am hoping not to have to replace the gas tank.

Here are some specs, 3.5in lift on 35s - I have been running this setup for over two years without any issues until now

Any help would be awesome!

Could be a couple of things. When I had this issue, I replaced the little white can on the back of the evaporated canister and it fixed it. I have read other threads that suggested that the evaporated vacuum lines that run up under the hood next to the battery could have a small leak. OPEN wrapped it in electrical tape to fix it.

just got mine out of shop got a new gas cap and they did a smoke test and i forgot what it was called but it was a little piece for like 200$ and it was fried so they replaced that no problems

Under the hood or under the jeep?

Underneath it was dealing with the fuel system near the gas tank. I cant think of it

was it the evap can?

Chantheman74

if its 200$ for just the piece then yeah. it was something towards the back

I did the smoke test when I kept getting this error. The smoke showed a leaky oil fill cap. I replaced it and no more error.

How did you do the smoke test? Where did you connect the smoke?
