I would only do it if they are offering high quality stainless steel. Mainly because SCTA told me I had to change a fuel line out for stainless steel because it wouldn't pass safety inspection lol.

im starting to have this problem too.... :( im over 80K and im pretty sure my cat is dead....but how do i check if the fuel pump is ok or not ? im getting a headache from the smell...it is SO Bad

you will need to take the rear seat out and check it.
