I don't have a 3.6 but from looking at it looks like a high pressure fuel line.
All the lines I'm finding are way longer Than this one. Its a short line![]()
I did see that on a website but I'm not sure. It looks like it could be but the diagram doesn't show what it's attached to. It could be

"High pressure" and "rubber tube" do not belong in the same sentence, lot alone the same circuit.I have the same issue on my 2008 JKU. I had it at my mechanic since I've never worked on fuel lines and he said that part isn't available anywhere until sometime in later summer of 2023! He made a temporary repair but I'm still looking for a better solution.
If you get high pressure fuel line for fuel injection engines, could you clamp a piece of rubber tube in place of this? Has anyone come up with a good replacement option?
Now you're talking about a custom made high pressure line. That would work, since you'd be paying someone to hand make the same product you'd buy (if you could find it).How about a fuel line that meets SAE J30R9 standards for high pressure injection lines rather than "Rubber"?
