Jeeps totalled. I'll give ya 500 bucks.








I keed i keed! Give us some info the jeep and when the code set. Evap codes can set from leaving the ignition on/running while filling up with gas, "topping off" the tank(putting too much gas in), running out of fuel, etc.

Cracked lines are a very common culprit as vehicles age also.

Aaahhh funny guy!! Ha well I had a fat misfire about 2 weeks ago. Changed my plugs to copper cores and it fixed it. Ran like a champ. Reset the codes (evap large leak, cylinder 6 and 1 misfire) then drove at least 200 miles to go through drive cycle. At about 210 miles it came on as just the large evap leak. One thing I do need is a water pump. I can see it leaking from the top. But that couldn't be it could it? Other than that. Everything is great. Thinking about just switching gas caps with my other jeep and see if that changes anything. What else could she be?

I would do that and check all the rubber lines from the tank to the front of the truck. More often than not they crack or come loose over time. If that doesnt clear it, i would see if you could get a shop to smoke test it for you on the cheap.

Alright cool. I got my hands on a smoker so I won't have to deal with a dealer. Thanks for the help

Dropped the tank because my fuel pump went out... If its not one thong its another... Found a hole in the top of the tank from a screw that got tightened down too far in the back of the ol hog. Thanks for the help guys
