Last week my 06 liberty CRD developed a leak on fuel filter side 1/4 inch hose which had become leaky and brittle due to age. I tried finding part number from parts fiche but was. Unable to locate it so hacked a replacement tube and some clamps it held on for a few days and now the leak is back. If anyone can help with the part numbers for this job much appreciated. Thanks

You need to clarify exactly which hose (fuel or coolant). If fuel any good fuel line of the appropriate size (I prefer marine grade diesel rated) will do. If coolant any good heater hose will do although there are some really small lines at the EGR cooler that might need to be replaced with CRD specific ones.

Use a good grade fuel line of same size. It is either 5/16 or 3/8 hose, cant remember for sure. Available at any good parts store. Just take a piece of your old hose for matching size. Be sure and refill cooling system with the G-05 coolant requirement.
Fuel line is rated for much more pressure than your cooling system will ever see!
I had to do this last year on mine before I removed the EGR & cooler and all associated hoses/plumbing this year.
