These rci fuel cells feature a number of important benefits, like seamless polyethylene construction for outstanding impact resistance and 360 degree mounting strap recesses. What differentiates these circle track cells from their drag race counterparts are a pickup hose in the right rear corner for increased fuel pickup during cornering, a flat bottom for easier mounting, and a cap. These circle track fuel cells are also available with an optional red powder coated steel safety can for increased crash protection.
