I see that someone has been banned by FII for tampering with their fuel breather non return valve. Fully understand that it is a dangerous thing to do and not going to question the ban but what I'm struggling to understand is what benefit tampering with the valve gives in the first place???

Not a ban, just lost his place in the race due to having an illegal car.

Reason people have been tampering with them is they are said to be temperamental at times resulting in fuel starvation.

some people arent fitting them properly meaning when the fuel starts to deplete the engine cuts out, so they drill out the insides of the valve so it looks like its fitted, but doesnt actually work

when cars go over etc, the one way valve stops fuel from coming out of the breather pipe

Was the case in the early days, several were caught out by fitting them the wrong way round.
But the people knocking the middle out now are experienced drivers.....so I hear.

Thanks guys. Got them on my boys' cars and know they can create a vacuum if fitted arse for elbow but would never think of drilling out the valve as the consequences of a fuel leak upside down don't bear thinking about... Surely it must be simple to turn it round rather than tamper with them???
