Its not uncommon for these fuel coolers to rust, leak or get damaged. There location under the truck exposes them to elements and may cause them to rust or corrode over time. Its always best practice to consider replacing the fuel cooler during any major fuel system service or replacement. Fuel coolers often trap tank debris and rust which can lead to fuel system contamination if not cleaned or replaced.
