First locate the distributor which is somewhere near the back of the engine and it will be sitting on the fuel rail. Beside the distributor will be a metal tubing and this tubing will have a cap or a valve that looks similar to the ones that are used to inflate tires. That is the valve.
Loosen the gas cap. Look for a Schroeder valve on the fuel rail and relieve pressure there. If there is no Schroeder valve, then there is no pressure relief. You must be prepared for the spray of fuel when you disconnect the fuel line.
