Fuel tanks need a vent hose and the go-to hose for pro teams and racers is the Free Flo hose system.
Made of a nearly indestructible kink and fuel resistant vinyl rubber they feature a check valve to prevent fuel from leaking out of the tank with the bike on it's side.
- Check valve hose is 1/4" x 18"
- Black, Red, Blue or Florescent Yellow
