Fourby Friday - Hilux fuel tank vacuum issue

Toyota Hilux (and possibly other utilities) blocked fuel breather issue.
Fuel error/warning light came on. I thought the issue was water in the fuel filter. After emptying the water catch the light remained on. Upon opening the fuel cap it just about sucked in my arm from the extreme vacuum the tank was under.
Watch the video for the solution.
I will be making a cover for my fuel filler, not sure why this was omitted from the tray design, mine is completely exposed to anything that the tyre throws up.
