So I was under Jeep yesterday and seen this box located drivers side under about the rear seat, I have a broken hose coming out of it and looks like it leads to fuel tank? Does anyone know what this box is and how important this hose is since it is snapped off at the box and not sure how to fix without replacing box? I'm thinking emissions related but no codes are popping up. Thanks for any ideas.

I think its the pump to pressurize your tank, do you have a CEL on?

 

No.

Evap Canister. Like athenscj5 posted the link to.

 

I appreciate the info sounds like the EVAP box, I looked through FSM also and could not find anything. Thanks!

 

haha

Talk about a thread highjack!!!

 

All childish BS aside what is it? I might want to relocate mine inside under the rear seat.
