I have the 05 and no that mine is in the tank but a friend of mine has an 02 trailblazer and lives about 200 miles from me. I thought hers would have the standard fuel filter mounted on the front of the tank but good ole jiffy lube said yhey didnt see one. Is it possible for her to have it in the tank like the 05s or is it behind the tank shield? any thoughts. Thanks
