Fuel Tank? Aerotank? Other?

[elks]

So I have been searching. At one point I was heading towards a Northwest Fab tank. But they no longer make tanks. I see that Aerotanks make a 40 gallon tank.

I am running throttle body injection on a 5.7 with an external pump. No big deal.I want to get to 30+ gallons as I am always hunting and it gets old packing gas everywhere.

I see where some say you can use a 87 tank, but I really want a full write up. I am not against having a custom tank built if I just had good dimensions. The PO on my blazer used a 16 gal fuel cell. Does not make it too far from home.

So links to an aerotank install, or a late model tank install. I want to keep my factory fill location.

I have found several threads with bits and pieces, but not a complete build thread.
