There are several posts about this if you do a search.
Surprised that you went that long with a Fuel Safe cell.
I pulled my 42 gal tank and bladder, then sent the tank to Nick Acton (Mickmate) and had him install baffles etc in the tank and weld it all up. No more fuel cell.
Fuel Safe says 4 years for their cells and wait until you get a price for a new one!
