EVAP failure on 2005 Kia Spectra5

what is an "EVAP" failure, where is it located and how do you replace it?

Asked by for the 2005 Kia Spectra5
The EVAP is a complex system, including many parts. You won't be able to diagnose it without diag. computer and good knowledge about the system, sometimes it requires smoke pump to check leaks. I have seen techs failing to diagnose the system properly.
Take it to pro, have it diagnosed the system, than replace only the necessary part.
Otherwise it will cost you higher $$.

It is located at the rear and center of the fuel tank and is easy to remove, but hard to replace. The part is $114!
