Relieving Fuel System Pressure

Print

This system incorporates a bleed in the pressure regulator which automatically relieves pressure any time the engine is turned off, but a small amount of fuel may be released when the fuel line is disconnected. To reduce the chance of personal injury, cover the fuel line with a shop cloth to collect the fuel, and then place the cloth in an approved container.
