Evaporative Emission Line Replacement - Engine to Chassis

Warning: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.

Warning: Do not allow smoking or the use of naked flames in the area where work on the fuel or EVAP system is taking place. Anytime work is being done on the fuel system, disconnect the negative battery cable, except for those tests where battery voltage is required.

Warning: Whenever fuel lines are removed, catch fuel in an approved container. Container opening must be a minimum of 300 mm (12 in) diameter to adequately catch the fluid.

Caution: Fuel/Vapour lines cannot be spliced or repaired. The line must be replaced (if damaged) with the same type of line.
