One Way Valve

 Fuel Line One Way Valve.

Allows fuel etc one way only.

As used in BriSCA F2 on the fuel tank breather, to prevent fuel spillage in the event of a roll over.

8mm tails.

From 2010 the use of this or alternative solutions is mandatory in BriSCA F2.

We reccomend the use of a short piece of hose or small air filter on the "open" end to avoid dirt ingress which may obstruct the effectiveness of the valve. When fitting the orientation will not affect the operation of the unit. The arrow should point TOWARDS the tank indicating the direction of flow (in this case of air INTO the tank).

Can also be used to stop fuel syphoning back from carbs etc when used in the fuel line, it is not just for use as a breather valve.

Please note that this unit is in no way endorsed for use in FIA or MSA sanctioned motorsport for use as a roll over valve, it is however accepted by BriSCA as a suitable device to comply with 2010 regulations.
