Thank you DmaxMaverick, I will take a look at it. After watching fuel filter install videos there are a couple things they possibly did incorrect. As you mentioned the o-ring, the bleed screw and improper purging. Just makes me a bit mad that they did not drain the fuel out of the lines. By the sounds of it there was still a fair amount of unleaded in all of the lines and possibly the tank. They didnt drop the tank when they drained the fuel. I only hope when they were driving it there wasnt damage done and what Im dealing with is just that.
