Protect your fuel bladder with Radium Engineering Fuel Cell Cans, designed as direct replacement outer cans for Radium RA-Series Fuel Cells. Built from black powder-coated aluminum with stainless hardware, these cans provide structural protection, impact resistance, and long-term durability. They are not compatible with older FuelSafe or non-Radium bladders and must be used with an approved bladder. Ideal for motorsport vehicles needing certified, replacement fuel cell housings.
