And take note of the copper washers that should come with the new filter. If I remember it right, there should be 4 of it. You will know where to place them once you get to start working on it. Pay attention to what you are doing so you won't get anything in the wrong position or something of that sort. I didn't relieve the pressure when i did mine so I was sprayed with some fuel while doing it. Get some plastic sleeve to wear on top of any sweat shirt so it won't get into your skin because it burns I'm telling you. Before you put the new washers on, i suggest that you get a sand paper and just sand the surface of the washers, both sides, you can put the sand paper on any hard flat surface and then run the washers back and forth. This will assure a good seat on the connectors where you'll use it on. You'll see. Check the washers carefully for any dent because, just a small dent can cause some serious leak. I don't remember using that special tool described on the previous message, I remember using regular wrenches. Wear a goggle by the way.
