This post is follow up to HOW TO: fix the KJ fuel burp plague! (https://www.jeepkj.com/threads/how-to-fix-the-kj-fuel-burp-plague.57056/)
For my 2009 Liberty (KK), process is different. I'd say easier than on KJ.
So on the KK, the inlet to the fuel tank is mostly aluminum line. There is a short length of fuel hose from the aluminum line which connects to the fuel tank. I replaced the original hose with the Genuine GM 15131046 Fuel Tank Filler Hose from amazon.
Here's the process I followed:
I hit each end of the hose w seafoam's deep creep and let it sit for about 5 minutes. I removed the old hose. Not alot of room to move here and the spare tire was in the way a bit too. Removing the old hose took the most amount of time. I considered just cutting the old hose off, but decided to keep it intact in case i need it later. It probably took me 20 minutes to work the hose out.
I cut the new hose to be same length as original mine was 7". The section I cut off was JUST on the end WITHOUT the hose clamp. I am still concerned that I don't have enough length of hose from the end of the hose to the valve. I considered pushing the valve further up in the new hose. I decided to just leave the valve in the factory location.
There was enough length of hose to allow me to reclamp on to the aluminum line. However, I still need to test if there is enough room for the valve to move fully. I guess I'll find out on next fill up.
When I installed the new hose I rotated the hose so the notch in the new hose was on TOP of the fuel tank nipple. You can see the notch in the new hose in the pic with both hoses side by side. I added the red arrow to help identify the notch.
I did not have to remove any parts to do the swap. However, I probably should have removed the spare tire to give myself a little more room.
I DID remove 1 bolt to allow the aluminum line to move.
NOTE the GM hose has a notch that needs to be located at the TOP of the fuel tank nipple.
I'll update here on the forum if there are any problems with fueling up or any other issues by just using the GM hose.
