: When I put fuel in my car, there is a slight, but very noticeable, positive pressure in the tank.
> Ae yoy sure its positive pressure ? Mine has negative presure which makes more sense (fuel is being pumped out at a high rate :-( )
: Is this normal to the breed?

> I've had other cars wich showed the same phenomena
> If the presure because to low inside the tank it will becomre difficult to pump out any more fuel so the engine will 'starve'
My bike will show positive presure when exposed to sunshine (which heats up the (black) tank). Even the venting hose won't help when it's very warm outside...

hope this helps...
