You will have a sudden short spray of fuel when the pressure is released. Just wrap a rag around the connection and be prepared.
Remove the gas cap and that will relieve pressure in the tank. There is a Schroeder valve on the fuel injector rail. Use that to relieve pressure at the injectors.
schrader valve on fuel rail
find the schrader valve on the fuel rail depress the stem and it should release the pressure from the fuel system
Remove the fuel pump fuse or relay while the engine is running. It will relieve most of the pressure once the engine has stalled.
Look for a Schrader valve on the fuel rail and press it to relieve pressure. If there is not one remove the fuel cap and then be prepared for a small spray of fuel when you disconnect the filter. Place a rag around the connection before disconnecting it.
On the fuel rail that feeds the injectors there is a cap. It looks like a tire cap. That will reveal a schrader valve that you depress to relieve the fuel pressure.
Remove the gas cap. If you do not hear the pressure release, then press the shrader valve located on the fuel rail.
First loosen the gas cap and relieve any pressure in the tank. Now look on the fuel rail for a schrader valve and push it to relieve the pressure. It will look like a tire valve. If you find none, then just be prepared for a spray of fuel when you disconnect the fuel line. Wrap it with a rag to prevent the spray.
Remove the gas cap, and look for a Schroeder Valve on the fuel rail. If it has one use that to relieve pressure. If it has none then you just must be careful and expect spraying gas when disconnecting a fuel line.
Remove the gas cap, and then look for a Schroeder valve on the fuel rail. If there is no valve, then you cannot relieve the pressure. Just be prepared for a spay of fuel when you take the fuel filter off. Wrap a rag around the coupling as you loosen it.
Depress the Schrader valve on the fuel rail mounted on the engine. It looks like the valve stem on your tires.
The fuel pressure regulator is located on the fuel rail for the injectors. It should be right on top of the engine, and it will have a vacuum going to it. It is attached to the rail with two or three screws. Remember to relieve the fuel pressure first if you are planning on changing it.
