Misdiagnosed gas tank replacement
I brought my 2011 JKU Sahara to a mechanic for an inspection. The check engine had just come on but I had to get it inspected and I pulled the codes and got a code for the ECS. Mechanic manages to clear the code for the inspection but tells me the vent hose for the gas tank is cracked, the tank needs to be replaced and this is a common problem in the jku(I've never heard of it)
I purchased a new tank from quadratec ($700) but in the weeks it took to come in the check engine light has never come back on? Tank just arrived and is in my garage. Anybody ever have a problem like this or hear of anything similar?
