Fuel spills fuelling up, tank leaks when full

[sunman]

Gentlemen we are playing with gasoline here
On the street
EFI systems are sealed with pressure in the tank
Carbs have vacuum in tank as a result of pump sucking gas and air is sucked in thru a vent
It’s not vented to let air out
Vented gas caps are one way, in

It’s two different worlds
