8. Fuel Hose on 1979-1987 XJ6

Ok, straight from the shop floor: This week's tech bit is about the fuel supply hose line on a 1979-1987 XJ6. 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. You can buy good quality fuel injection hose at any local parts store, and it's usually about $2/foot.
