I followed the tutorial and the entire DIY went totally trouble free...which is actually kinda unusual. Tips for purging fuel line and charging the fuel filter in the end worked great. There was very small amount spill from the big front tube. Most of the gas was from the old filter itself, and nothing came out of the twin tubes from the back. I concurred with the writer that the hardest part was getting the big front tube off. The other steps were not too bad. Again, great tutorial. Thanks alot!
