Some car repair shops, such as Austin's Pro/Max Radiator, Muffler and Brake Service Center branches in Washington, offer repairs for your car's gas tank. You can also purchase and use the Permatex Fuel Tank Repair Kit for minor do-it-yourself repairs, though the aid of a professional is still advisable.
As of 2016, Austin's Pro/Max Radiator, Muffler and Brake Service Center locations are Tacoma, Puyallup and Spanaway. Among the gas system services the business provides are repairs of malfunctioning sensors, broken fuel lines, rusted gas tanks and dual gas tank problems. The company also flushes gas tanks to remove contamination. Austin's Pro/Max provides free gas tank inspections and guaranteed gas tank parts and labor, and provides repairs for many types of cars, trucks, vans, SUVs and RVs.
