Fuel tank vent

[Josh]

Hi all

I'm having a hard time working out how do let my fuel tank vent air both ways whilst preventing fuel leaks/spillage. I've found this http://www.carbuildersolutions.com/uk/bolt-in-fuel-tank-breather-valve but I'm wondering if there is a 'locost' way of doing it that is still good for the IVA?

Thanks
Josh

That's what I used but the one that goes on to a piece of hose. Not cheap as it was more than the one in the link.
I did originally buy a cheap 1 way valve but it won't allow for expansion when it needs to behave like a 2 way valve

I used a long piece of hose that runs from the vent nipple on the rear right of the tank up to the top of the rear tub, then all the way to the left of the tank, then front and then down, strapped to the diff cage somewhere. This way it's not spilling when cornering left or right, braking or accelerating with the full tank, and hopefully will not spill upside down.
