8. Fuel Hose on 1979-1987 XJ6 XJS
Jaguar Parts Technical Information
Ok, straight from the shop floor: This week's tech bit is
about the fuel supply hose line on a 1979-1987 XJ6 XJS.
This fuel hose may touch the
battery on its way to the fuel rail. We just had a car in the shop with
a fuel supply hose that had been partially eaten away by battery corrosion,
and had swelled and was ready to burst. Can anyone spell FIRE? Check
yours today. In general, the fuel lines under the hood are in a hostile
environment and deserve regular inspection. The heat tends to harden
and crack them, and over time they will develop splits. The clamps
will also loosen over time, allowing fuel to leak past the ends of the hoses.
Fuel leaks WILL BURN YOUR CAR TO THE GROUND!
This isn't idle speculation, this is a regular occurrence, particularly
for the V12 cars. When replacing this fuel line (a good idea, if yours isn't
new) be sure to use only FUEL INJECTION hose. It's expensive because
it's reinforced to withstand the higher fuel line pressures required of the
fuel injection system. Regular fuel line will bleed through, allowing
fires to start. Remember, if it seems reasonably priced then it's the
wrong stuff. We sell the correct fuel hose by the meter on the website.
