Quick Refueling Without Breaking the Bank

Inspired by OEM "Capless" fuel fillers, Radium's fuel cell swing-valve fillers use a spring-loaded valve to allow quick filling at a competitive price.

This capless filler mimics modern OEM fillers and swings open when a filler nozzle is inserted. Nothing has to be unscrewed.
