Rockauto is about 7 days with from order to letterbox, slowest part of the journey is AustPost usually, ordered last 3 weeks ago 7 days.....
I would never take much notice of what Jeep says about parts, the nil stock world wide is often thrown about, the parts take so long to get here because until the container is full it aint leaving the US ...............
I would hazard as stated before reusing of the fule lines doesn't mean they are going to blow, but the crush washers will need some TLC, a lot of things Jeep (and other manufacturers) say can't be reused or dismantled, is more for ease of maintenance than a part failure........ The engineers that designed these things aren't all that bright, just look at the cross member on the auto for example, just a dumb position.....

Available in the US....................of course with these places you will have to use the AustPost Shopmate, unless Rockauto has it listed then they will ship direct to Aust often way cheaper than Shopmate.
Since the yank 2013 didn't have the V6 diesel you won't find it on listings other than export model.......and sometimes for engine bits you need to call it a Limited instead of a Laredo.
