Medium flow fuel tank breather valve from Mocal. It has capacity for cars with a moderate fuel consumption rate. This valve simply fits into your fuel breather pipe from the tank to atmosphere. It is straight through in-line vent/roll over value with 6mm male tails both ends. Without a breather valve, a fuel tank cannot replace the space left by the reducing fuel and a vacuum tries to form. This makes it hard work for the pump to suck it out and the tank could collapse inwards. These valves allow air in as the fuel is used, yet close off should you roll over or if fuel tries to exit from the valve itself, due to the ball valve which closes when inverted or if pressure is applied, a useful and sensible safety feature.
