The interior foam should be replaced every few years.

20 years on the same bladder is a lot! Usually 10-12 years is about it.

Either Fuel Safe or ATL have FIA FT3/5 approved bladder and can systems and both are nice people. They both now have (and Fuel safe has had for 2 years) an FIA FT3 rated less expensive plastic bladder/steel can.

Sidelightem.....there is a big difference betewwen these units and the blow molded pieces with the bail handle cap made by JAZ and others. Visually if the unit has a fill plate with cap/fill tube /flapper/and a inlet and vent with one way valve on the fill plate then youve got the real deal.......there is not adaquate protection in high impact or rollover situations with the blowmolded/non fill plate pieces.
