So have PO455 and PO456 trouble codes coming from my 2014 MDX. Took it to the dealer who was able to diagnose a leak in the evap fuel line. The car is not leaking fuel so I'm assuming this is for gas vapors. He said the line itself is not sold seperately from the tank so they would have to replace the entire fuel tank to the tune of two thousand six hundred bucks. Does anyone know if the hose can be replaced or repaired/sealed? This seems like a ridiculously high expense for such a simple problem. I just can't stomach dropping that much money for something like this. Thanks.
