The answer on that topic is the typical "it depends."

I am not sure that any type of FIA-labeled cell is safer for street driving than the stock tank.

But I do know that the car was designed in Germany with both safety and various gubmint regulations in mind.

I have a '75 that has a fuel cell. The bladder is over 20 years old and it is fine.

It is configured as a race car, but I can drive it on the street as well.

I run high octane leaded fuel, and all fueling is done at my home.

some truth there. I have two race cars with cells. One is quite old in the 914/6 (enduro cell also) and still in good shape. I have one that timed out in 2019 (new in 2014) and it is a terrible leaky mess. Fuel safe says times out after 5 years. I've heard you can get them recertified if in good shape but no experience. I've also heard of problems arising before the 5 year term date.

I still don't see the need for one on a street car.
