Hello all this is my first post so please have mercy on me (LoL) Got a code for evap leak and found the metal line on the rear gas tank to canister is rusted out tried to find another one online but did not anyone eles have the problem and how did you fix it I would like to replace line and rubber hoses on both ends

 

You can buy metal fuel line and rubber fuel hose at any parts store like NAPA or Advance. Just get the size and length you need and use that.

 

Welcome to the forum, johnboy21. When asking for assistance, it would help us to know the model year and engine type of the jeep.
Usually with an evap leak code, again - which one?, it is recommended to replace your gas cap first with a Mopar cap.
If the fuel vapor line is toast, then you can make your own as Ben suggested or you can probably get one from the dealer. (It will come with the rubber connectors.) I bought one when I was trying to solve my evap issues. Depends on your wallet and/or mechanical skills.

 

Thanks for the replies. My XJ is a 1999 limited with 102k got it for my sons first car. he loves the cherokee I have been driving it just to shake out any problems before I turn it over to him and he was spot on it is a very cool ride.I think if I get this squared away it will be good to go. I do not remember the code # but is is for gross leak and is intermitton can reset and CEL stays of a few cycles or days. while I was replacing the rear brake line I noticed that the tank to canister line was in rough shape also the rubber connections feel very "spongy" also.I tried to find the OEM line and have not found. if anyone knows that I would gladly get the correct part can post actual code # tonight and thanks for the help these emmision leaks can be a bear to correct.

 

The part number for the fuel vapor tube for the '99XJ is 52100 162AE.
Also follow that line along the driver's side towards the front of the jeep. Just about under the driver's seat, two plastic tubes are joined by a three inch length of rubber tubing. The rubber tubing can get disconnected causing an evap leak.
My kids also wanted the Cherokee to drive. My daily driver is the Sport. Every once in a while, I give myself a treat and drive a Limited.
