Frozen fuel lines are caused by condensation and moisture in the fuel tank. This can lead to ice build-up in the lines, which can cause the engine to sputter and eventually stop. Fuel line antifreeze can be used to prevent this issue.

What You'll Learn
Condensation in the fuel tank
If your fuel line freezes, ice can form inside, causing the engine to sputter and eventually stop. The frozen gasoline elements also create a thick liquid that can clog the fuel filter and contribute to engine sputtering. The engine may start but stop suddenly due to icy buildups blocking the fuel from reaching the engine.
If you're lucky enough to get your car started, the icy buildup in the lines may cause the engine to sputter. This is because the system is getting enough fuel to run, but not enough fuel to run properly or efficiently. Allowing the engine to run for a while to warm up while revving the engine a few times may help the sputtering problem. If the lines can’t get warm enough to get rid of the icy buildup due to severely cold weather, or too much air in the lines, the lack of gas could cause the car to stop or stall.

Fuel line antifreeze
If you live in an area where moisture in your fuel is a recurrent problem, or where temperatures dip low enough to cause this issue, adding a bottle of fuel line antifreeze at every fill-up is a good way to prevent future problems.
If your tank is low and you have a frozen fuel line, sometimes adding three gallons (or more) of gas can help dispel the cold air in the tank and lines that’s helping to cool the fuel. If the tank is near full, however, this won’t help.

Engine sputtering
Frozen fuel lines are caused by condensation that accumulates in the fuel tank, otherwise known as water in the tank. This can cause the engine to sputter and eventually stop. The ice that forms inside the fuel line prevents enough fuel from reaching the engine, causing it to sputter. The frozen gasoline also creates a thick liquid that can clog the fuel filter, which can also cause engine sputtering.
If your fuel line is frozen, adding three gallons of gas can help dispel the cold air in the tank and lines, but only if the tank is not near full. Fuel line antifreeze can also be used to absorb moisture in the fuel lines, which is often enough to get the gas flowing again. It can also be added at every fill-up to prevent future freezing.

Fuel filter clogging
Frozen fuel lines are caused by condensation, or water in the tank. This can lead to fuel filter clogging, which in turn causes engine sputtering. Fuel line antifreeze can help to prevent this issue.
If you live in an area where moisture in your fuel is a recurrent problem, adding a bottle of fuel line antifreeze at every fill-up is a good way to prevent future problems. Fuel line antifreeze is an alcohol-based fuel additive that absorbs any moisture that might be present in your fuel lines.

Low fuel levels
Fuel line antifreeze is an alcohol-based fuel additive that absorbs any moisture that might be present in your fuel lines. Since moisture is the primary cause of a frozen fuel line, removing it from the equation is often enough to get the gas flowing again. If you live in an area where moisture in your fuel is a recurrent problem, or where temperatures dip low enough to cause this issue, adding a bottle of fuel line antifreeze at every fill-up is a good idea.
