What happens if there is too much pressure in the gas tank?
Fuel pumps feed fuel to engine carburetors by pumping it from fuel tanks. Removing fuel causes a vacuum that, if not released or maintained at the correct pressure, becomes too great, causes pump failure and starves the carburetor of fuel.
Why is there no leak in my gas tank?
The tank leak immediately stopped dead, but I feared the tank had developed a micro crack from the pressure that simply did not leak noticeably under normal pressure.
How does vapor pressure build in a gas tank?
Vapor Pressure Builds From Heat. The gasses released from liquid gasoline in a sealed container (the gas tank) are directly affected by the temperature of the gasoline; the higher the temperature is, the more pressure builds in the container.
How does the temperature of a gas tank affect the gasses?
The gasses released from liquid gasoline in a sealed container (the gas tank) are directly affected by the temperature of the gasoline; the higher the temperature is, the more pressure builds in the container.

Where does the pressure go in a fuel tank?
fuel vapors [pressure] goes into the canister. the fuel cap allows air in not out. this is how it works.
What causes a gas tank to bulge at the bottom?
If the fuel pickup and level float are anchored to the top of the tank, plus pressure buildup causes the tank to bulge at the top and bottom…. the pickup and float could be lifted from the fuel, changing the gauge and starving the engine.
Why does my gas tank smell like gasoline?
Gavin reported to me his fuel tank fill cap, when removed, will have fumes blowing out continuously under pressure as cap removed. The sound and smell of gas vapor will go on for an extended period of time, not just the normal short hiss. Fuel smell is filling cabin at times, while driving. At times gasoline smell comes from under the hood.
