Gas Tank/sump - will it pass tech?

If it was my car I'd sell the tank to someone that could use it & either get a new tank sans sump or use a trunk monted fuel cell.

Why? and what does that mean someone that can use it? You back a car into the wall hard and I would just assume the fuel dump in the ground not all over the inside trunk of the car by the battery an ignition source. Even with a typical fire wall panel behind the seat there is still openings in the quarter panel area's and rockers where fuel and fire can get to the driver.
