Tank Tip #2 - Overfill Prevention

Fuel tanks are designed with a vapor space for the expansion of fuel due to changes in temperature and elevation. Overfilling a fuel tank can cause serious problems. When a tank is overfilled and vapor space is not maintained, fuel system sensors may trigger a check engine light, distance to empty calculations may become inaccurate, and tanks could even leak - creating a fire hazard. To avoid costly diagnostics, Transfer Flow recommends the following procedure:

• First, park vehicle on level surface and turn off engine
• Slowly remove the gas cap to release vapor; then insert nozzle until it stays in place without support
• Squeeze handle to maximum flow rate and fill until first automatic shut off
• Wait 10 seconds for vapor equalization, then reengage nozzle
• Do not continue after second automatic shut off
• Remove nozzle and replace gas cap

Follow this simple procedure and you'll spend more time on the road and less time and money on repairs. For more information on proper fueling procedures, or a Transfer Flow fuel tank for your vehicle, call us at 1-800-442-0056, or check us out online at
