I originally wanted to have someone else do this repair for me because the rear hoses that were leaking run inside the frame rails and are difficult to access at the sides of the fuel tank. Also the AP numbers were completely gone at the control side of the hoses. I first started to measure the lines, but then I found the AP #'s somewhat visible at the rear jacks. I removed the white tags and cleaned them so I was able to order the OE hoses from HWH.
I used a 1/4" pipe nipple to thread the front of the new hose to the rear of the old hose and was able to pull the new hose all the way up to the front. I had to cut off about 40 zip ties to get the lines out, then installed 48 new ones.
What a relief to have my jacks working again and only cost me about $160.
