of the tank. These tubes are in turn connected to the fill pipe of the gas tank via a 2 3way tees and the plastic tubing aforementioned earlier in this article. The venting system is there to allow air into the tank to avoid a vacuum as the car uses its gas supply and also to vent the tank when heat expands the gas vapors in the tank as well.

When a fluid is pumped through a pipe, the magnitude of the electrostatic charge generated will increase as the velocity increases. When this liquid is transferred into a smaller pipe, the liquid velocity will increase as will the static charge. When a filter is placed in the pipe, the static charge generation increases by a factor of 10 to 100.

You'll also see this where gas comes into a house, the connection between the meter and the house will have a a couple 90s on the same axis offset a foot or more. that allows the meter to move up and down relative to the house without the pipe breaking off. The 90s acts like a hinge. posted by Mitheral at 3:05 AM on Ap

Fire & Explosion Risks in Service Stations

Service Stations Petrol Vapour Petrol gives off highly flammable vapour even at very low temperatures. Because of the flammability of petrol vapours, service stations carry a risk of fire or explosion not common to other types of retail outlets. Ignition of petrol vapours can happen if vapour comes into contact with a heat source capable of igniting it.
