Joe-
Many thanks for these informative posts and pics. WIth so many asking about ank relocation, it is most helpful to see the pics and get the description. I should note that I am not getting the first 4 pics on part #2. You might edit the links.
I really like your filler location. I am in the process of planning this aspect of my rig, with the tank in a similar position. The side-mounted filler is an interesting option. Hope you get enough down force to fill at a rate equal to the output of most nozzels at the pumps these days!
What is the external cap going to look like in the end?
Thanks again!
