A 42 gallon Fuel Safe fuel cell is good for 4 years, then goes to hell.
Replacement cost is over $4k and that's just for the new bladder and internal foam, not to mention work to replace it all.
How do I know this?
Pulled the tank, pulled the cell, had it welded up with internal baffles, isolated pickup area etc.
If I race it, then I will deal with that.
