I agree it is a good idea if you install and plumb it correctly. I think the best thing to avoid the catastrophic fire is a FIRE SYSTEM. Most factory installed fuel tanks are very good especially in the last 10 or so years. I have not seen a ton of cars catching on fire on the highways because of a rollover, they do take this into consideration on the OEM side. As long as your not racing older Chevy trucks or Pintos they seem pretty good. Most of the fires I have seen have been aftermarket part failures or not so good installations of aftermarket pumps and filters etc.
