anti siphon valve:

it's a ball and a spring - negative pressure is required to un seat the ball allowing fuel to flow.negative pressure comes from the fuel pump


without the antisiphon valve,if a fuel leak develops after the fuel tank - fuel can and will continue to flow - siphon action.


when you see a collapsed primer ball - that shows a restriction on the fuel supply - 9 out of 10 times,the antisiphon valve is stuck,that causes the primer ball to collapse...
