1 x 7111.  Correct breather hose for LATE Jaguar XK150 models, with the breather exit tube out of the side panel of the tank (also acts as fuel bleed-back from corner of tank catch tray). The correctly moulded bends prevent this pipe from blocking up and allows fuel spillage to safely  flow back to the tank from the catch box.

NOTE: These are the correct fuel immersible spec. rubber, so it will not dissolve as the fuel runs through it (droping rubber into your fuel tank as normal rubber hose will!)

This is only correct for the Later fuel tank that uses the half-ball type filler cap seal , SEE : 6660
