How to Prevent a Car's Fuel Lines From Freezing

What You'll Need
Fuel-line antifreeze

When outdoor temperatures dip below freezing levels and water vapor gets into your car's fuel lines, your fuel lines can easily freeze. Fixing a frozen line is typically inexpensive, but it can be frustrating to deal with. Instead, follow these simple steps to prevent the issue from happening in the first place.

Step 1 – Keeping Your Battery Charge at Maximum Level

To ensure your automobile's fuel lines don’t freeze, ensure your battery is fully charged. Small runs in your vehicle can lead to a drop in the battery charge. To keep your battery charged, don’t let your vehicle sit for long periods of time without being driven.

Step 2 – Maintaining Your Fuel System

Next, prevent your fuel lines from freezing by pouring a fuel additive into the system. Purchase a fuel-line antifreeze at your local automotive shop to add to your car’s system. Follow the manufacturer's instructions. This substance will keep your lines from freezing over, even at low temperatures.

Step 3 – Keeping the Fuel Tank at Maximum Capacity

In addition, Keep your fuel tank at its maximum capacity to decrease moisture in your system. The less moisture in the system, the less chance your fuel lines will freeze.
