Tyagi RacingNon Return Valve 1/4 inch 6mm Aluminium Check Valve

Fulfills the purpose that I got it for - to prevent petrol draining back from the carburettor (albeit it, it probably indicates an issue with my petrol pump which I will need to resolve, but will keep this valve fitted as well).

Purchased for a fuel line to prevent syphoning of fuel back to the tank and works very well. The secon one was fitted in teh breather pipe for the fuel tank to allow air in but limit fumes getting out. This worked very well, they are good quality.

Cant beat them for the price.

good valve
