1999 XK8 convertible How do I remove only the fuel line section that runs at the front of the engin between the two rails>

 

I think it is widely understood as a hard plastic part coated with rubber and is best not to be messed with for fear of breaking said plastic. I don't think that section is available separately and the entire fuel rail is quite possibly NLA depending on model. It is to be treated with utmost respect, and as if made of glass. At no time are you even supposed to stare at it too hard.

Best of luck keep us posted.

 

Hmmm...it's leaking from the drivers end (U.S) and I really don't want to replace the whole assembly for $658.00. I'm hoping I could just remove the line and replace with a new section of fuel line. The injection rails themselves are metal so I'm thinking a box cutter to split the foam and cut off the nylon from the rail.

I'll figure this out and post the solution I find.Thanks fmertz

 

OK!!! I've replaced the leaking fuel line between the fuel rails. Not really knowing what I was in for, I cut the fuel line and separated the two fuel rails. Since I now had a "loose" fuel rail, I took it over to my workbench and proceeded to see what's what.
Knowing Jaguar engineers for this car were ********, I carefully, gingerly cut away the foam covering to see how it was attached to the rail. The next step was to cut the fuel line itself away from the rail. Not knowing if it was a plastic or metal attachment point, I went in slowly. Turns out it is metal, and barbed like a standard hose attachment point.
I measured the fuel line inside diameter and it is 0.246. I went online to www.O'Reilly.com auto parts and found the barricaded high-pressure fuel line with a .25 inside diameter. A teensy tiny bit bigger but not enough to worry about. I bought a couple of high-pressure fuel line clamps, a length of hose, and proceeded to replace the fuel line between the fuel rails.

You can cut the original fuel line if you need to and replace it with a non-jaguar fuel line. Just make sure you buy the barricade type with a pressure rating of 241lbs Our cars need 40lbs, but the next step down is only 50lbs and that's too close to what the spec calls for. The cost difference is literally only one dollar at $4.99 per foot.

No leaks, no worries!!!
