Liberty XL2 anyone?

As I recall, the pinto and others had the tank behind the rear axle
where it was susceptible to a rear-end collision.

Every Ford auto from the Model-A through at least the 70s had the gas tank in that
location. Most other cars did too. The problem with the Pinto is that the rear axle
housing was designed in such a way that it could easily puncture the tank in a
rear-end. And Ford was aware of this. And Ford deliberately decided to do nothing
about it because it would cost a few dollars more per car to build a safe housing.
And someone leaked the memos about that.

Airplanes don't hit
tail first very often and don't get rear-ended all that often either.

And airplanes *really* hate having several hundred pounds of weight located around
the tail.

In Idaho, tossing a rattlesnake into a crowded room is felony assault.
In Tennessee, it's evangelism.

Having worked in a burn center, I also get nervous when fuel and my
skin are in close proximity. Diamond has approached the issue in a
different way than Liberty. My DA40 has metal tanks in the wings,
located between the two carbon fiber spars. The remainder of the fuel
system is external to the cabin. The fuel selector valve is connected
to the handle via long shaft, and resides, along with the boost pump,
in its own compartment.

To my knowlege, no Diamond aircraft has ever suffered a post-crash
fire.
