Need to have the body off the frame to pull all the lines. I only managed to remove from the fuel filter to the front feed. The rest of the stock lines are still in place.
I fed new lines from the front so I wouldn't have any slack up front. Once I had it to the back, I cut it from the wheel well area on the driver side with a cutting wheel. There's a lot of effort keeping the lines clean after cutting them. Can stick a dowel rod in it or don't just all the way through and only use the wheel to cut the metal and then a knife to cut the actual hose.
There's plenty of room in the frame to run lines, unless you are running -10 or -12 rubber lines, the Aeroquip TFE are narrow in comparison to rubber lines.
