d4ygl0...I used the instructions on Scoobymods. I did not empty the fuel system like others have suggested. When I disconnected the hoses a little fuel leaked out but not too much. The problem was that the filter itself was full of fuel and it spilled in my car on the way to dispose of it. If you have it, put a little grease on the new filter connections past the actual opening...it will make removing the hoses easier the next time. Good luck.
