So I just got my FCG alum. fuel cell, and its awesome! But I need help..... I know this topic has been covered alot, but I couldn't find the answers I was looking for in a search...... once I figure out where it bolts up in the frame, what is the best way to cut a filler hole? It will be straight through the floor of the bed, and I don't plan to have any fancy cover welded on or anything. Do I have to cut a big enough hole to get my whole hand in there and open the cap? Or can I make it extend out enough to where I can just pop a cap off up top. I don't know what to do!
Heres what my filler looks like
