I found that hose connecting to the intake right the throttle body leaking a few days ago. It was just pulled out slightly. I put a zip tie on it and my gas mileage shot up an extra 3-4 per gallon.

Thanks. 2014. Same exact problem. Broken. Fixed and cleared now.

[@ttermini]

Thank you!!!

That looks like a big leak to me. I bet the oem gas cap is long gone, swapped for junk, too.

Any idea how to get jeeps to rerun the evap test? I electric taped mine temporarily, amd want to get the monitor test to run. Fuel level between 20-80%, cold start the truck and get warmed up to temp, then drive on highway between 45-65mph without applying the brakes for a few miles? 😅. At least thats how my gm wanted the parameters, to run its evap test monitor...

[@davidcantrell64]

If you are talking about clearing the light on dashboard if you don’t have a scanner either drive it or pull negative battery cable for about 10 minutes or so should work

[@sidewayzmike]

Jjust want to verify my fix

I messed up a fuel vapor line on my jeep jk when I did a major tune up. Except the fuel vapor line on mine is connected to what looks like the transmission on one end and near the cars computer on the other. Any suggestions on how to disconnect it from underneath the transmission???

[@davidcantrell64]

Not sure about that without seeing it

[@jman2k0]

Electrical tape. Prolem solved lol

[@Chris-eh3yu]

Was the the purge house that needed to be replaced?

[@davidcantrell64]

[@Chris-eh3yu]

David Cantrell thank you for the response.

[@KjSaidSo]

Is it located in the same area for a Jeep grand cherokee 2016 by chance?

[@davidcantrell64]

Should be pretty similar location

[@KjSaidSo]

[@RuKuaj]

[@derelsantiago9550]

Where do you buy it? I have the same problem

[@davidcantrell64]

The dealer is only place I know to buy new one, but what I did was got a piece of vac/fuel hose and just did a slip over hose to repair mine, hope this helps
