How do you take pressure out of a gas line on a chevy silverado 2002?
On a cold engine I unhook the battery ground and then (if you are changing a fuel filter) just loosen it to relieve pressure. No matter where you relieve pressure, there will be spillage so use a drip pan. As long as the battery is disconnected the chance of fire is greatly reduced. There is a schrader valve on the fuel line on the engine for this purpose, but that can make a much worse mess cause it runs all over the engine.The MOST important thing is to disconnect the battery.
