I have an auxiliary tank on my '72 that is mounted on the driver's side forward of the wheel.
I have never used this tank and don't know if it is empty or what...but what I like about it is that the fuel fill orifice is within the wheel well itself.
When the side of the box is cut (or both sides?) and a pipe/hose run up through the box floor with that cut stainless door on the box side...those are the ones I don't like.
I can live with them if I had to....but I don't like the look of it.

That said, I'm guessing the ones that fill from within the wheel well were more than likely dealer installed....thank goodness, lol.

My two bits.
