IMPORTANT: Do not skip the fuel system pressure release step. Injury and other damage can result!
Safety Step! Relieving Fuel System Pressure
· allow engine to cool
· relieve fuel system pressure
· put on your eye protection
Before you begin the job of replacing your fuel filter, you must relieve the pressure in your fuel system. A fuel injection system operates under very high pressure. If you don't release this pressure before you start unscrewing fuel lines the result can be explosive. Do this before you attempt to change the fuel filter.
To release the pressure in your fuel lines (and fuel filter) you'll need to locate the fuel pump fuse in the fuse box. If you don't have a fuel pump fuse, find the relay that operates the fuel pump. Once you've found the fuel pump fuse or relay, start the car. With the engine running, pull the fuse or relay out. If you pulled the right one, the engine will quickly die. Since it's using all of the pressurized fuel in the system, the fuel lines won't be pressurized when you crack the fittings on your fuel filter.
Now that you've relieved the fuel pressure you can remove the old fuel filter.
If you didn't do this yet, you must go to the previous step and do it. Very dangerous!
