It dawned on me today, that my 98 XJ8 is probably 17 years old. At what point do we start concerning ourselves with how old the fuel lines are in these cars?
Have you guys been replacing them yet?
What's your timetable?

 

Should really be no need as these lines are designed for the life of the car.
Unless of course in your area it has been subjected to a lot of winter road salt and crud.
A good clean underneath each season with a pressure sprayer will help their survival rate and make for easy inspection.

 

Thanks for the reply xjay8. I just got the car, and I'm learning a lot about it now. Doesn't this car have any rubber fuel hoses? Certainly those need to be replaced at some point, no?
Thanks again for the help.

 

The fuel lines are powder coated steel, the same for the brake lines. Tough stuff.

If you get the car on a ramp you can check them, all fuel/brake lines run in a group along the inner chassis rail lhs.

If the powdercoat is compromised with corrosion on the lines then you could change them, but I'd be more inclined to change the fuel filter first, these things don't usually get replaced at a service mainly because they're a bugger to get at and the bracket bolt is generally rotten (at least here in the UK).

The system is a sound and solid design so I wouldn't be concerned about it as there have been no reports of failure or recalls etc that I know of, on here or with Jaguar, the nearest problem is 'in tank' fuel pumps failing and a new filter helps combat this.

Hope that helps!

 

I'd say that helped tremendously. I'm used to seeing some rubber on other cars.
Glad to know it's not a concern.
Thanks to all.

 

The only rubber sections on the fuel ines are under the bonnet/hood and they are desgned to last the life of the car.
The only rubber lines under the car are the brake flexible lines which should be inspected every year and if any look like they are perishing or show signs of cracking, the obviously replace.
This goes [practically for everything on any motor vehicle.....it's life is well extended by just simple, regular check inspections ;o)
Now...our Jaguars are built to an exemplary standard...considerably higher than many mas produced vehicles.

 

Thanks. I was never doubting the craftsmanship or engineering in our fine vehicles. I was just unsure of the the life of one of the particular materials.
I take it that the soft fuel lines are made of Teflon.
I have another car, also made with very high standards, but it is older, and it is imperative that the rubber fuel lines be replaced.
