New Braided Fuel Pipe to connect the solid fuel line from the tank to the carburetors. The item has the correct BSF fittings to connect to your Jaguar.
It's a good idea to replace this part if yours is over ten years old or of unknown age, as they can leak when they get older and the electric fuel pump will happily continue to spray gasoline all over the engine compartment from such a leak until you turn off the ignition (or if the car burns up and melts the battery).
We can supply practically every part you may need for your beautiful XK Jaguar. We have an XK ourselves and love it, so we speak the lingo firsthand. Call us if you need a part you can't find on the website and we will do our best to help.
