I depressurized the fuel system by pulling fuse 54 and running and revving the car until it died. This resulted in very little fuel spillage, what was spilled was just what was in the old filter. As I emptied the old filter, all the gas had black stuff in it, along with small particulate matter, like sand. The hose clamps are a bit difficult to close when they are covered in fuel, but you must use a pair of pliers. After everything was buttoned up, I let the car sit with the key in position 2 for a few seconds to build up the fuel pressure, but I still had to crank it twice. My service engine soon light was on, and the engine was running very roughly and had a significant loss of power. After driving around for about five min., everything was fine. The light went out and the engine was running smoother than before. Also, it seemed as if the engine was a bit peppier than before as a result of the new filter. I have just over 65K miles, so anyone in that mileage might want to replace theirs as well.

I should start posting anytime I do any sort of maintenance, it makes it so much easier to remember when I did it last!!

I think I have done this again since 65K, it is really a great DIY.

Be careful though.
