Gas Tank/sump - will it pass tech?

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.

Simple---some guys don't care about the safety of a modification as the car may never see a strip & be tech'd. Trunk mounted fuel cells have been used for decades & are far safer than any current stock fuel tank. Why? Because they have a bladder in them to control the spillage. The fuel seepage you're talking about would be so small the driver would have time to get out if the fuel was even burning.
