I have a 2009 T+C with 3.8 engine.There is a fuel leak at the fuel line at the fire wall.just had it in the dealer and they replaced the line.its still leaking,so much for quality control there.anyway is there o rings on the steel line or are they part of the fuel line.the line has a quick connect on both ends.I am thinking maybe there are seals on the steel line that need to be replaced and changing the fuel line fixed nothing.thanks for any help.
