i have a 2001 supercrew 5.4 i started to notice a smell of fuel from the truck i would always check it while it was off so i never saw any leaks. finally yesterday i checked it while the truck was running and found the leak its a little confusing but im going to try to explain it the best i can after the fuel filter there is a plastic line then after that there is a line out of tube and after the line of tube there is another plastic line well the leak is between the tube line and the second plastic line i dont know what type of fitting it is but i i havent been able to disconect the fitting i ended up cutting the rubber line but it dosent help cuz i still cant get the fitting any help???? i did try using the disconecting tool
