DURING EVERY FILL UP OF GAS, THE NOZZLE DOES NOT SHUT DOWN IN TIME AND FUEL SHOOTS OUT OF THE FILL TUBE ALL OVER ANYONE FILLING THE TANK AND ONTO THE GROUND. THERE ARE HUNDREDS OF PEOPLE COMPLAINING OF THE SAME THING, ALL WITH JEEP WRANGLERS. *TR

FUEL SPILLING AT EVERY FILL UP, FROM READING ON THE INTERNET IT SEEMS TO BE A VERY COMMON PROBLEM WITH JEEP WRANGLERS. IT HAPPENS AT EVERY FUEL STATION AND DOESN'T MATTER IF THE NOZZLE IS HALF IN OR TOTALLY IN. *TR
WHILE FILLING UP MY 2006 JEEP WRANGLER (TJ), GAS HAS COME SHOOTING OUT OF THE INLET FOR THE GAS PUMP NOZZLE.

How serious is the fuel system problem on the 2006 Jeep Wrangler?
It's a documented issue but not catastrophic. 360 complaints have been filed. Repairs average $1,200 and most owners catch it before it causes a breakdown.
At what mileage does the fuel system typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
