Hi Gents.
So, I decided to do a little good this weekend, and proceeded to replace my fuel filter. All went swell until I attempted to fasten the fuel lines back in the new fuel filter...with horror I discovered that one (fuel out) nut is stripped to the point of no reuse . Does anybody know what's the size of such fuel line nut, and possibly suggest a vendor? Below is PUB with the nut in question positioned next to the red arrow.
Any feedback is much appreciated.
Thanks,
Danny.

 

Uh oh, that's gonna be an entire fuel line segment to get that nut, its got to be a compression fitting. Check out the Gaudin jaguar online parts database and order system for a check on its replacement price. It may not be too bad.

 

*if* it is the same as the one on the X308 that lists the AC Delco GF-652 as a substitute, then 16mmx1.5mm is the thread.

You may want to check into repair parts from GM since that filter has been used on virtually every full size pickup, suv and van from GM since the mid 80's.
