Here is an older Chevrolet Suburban with a leaking fuel line. The vehicle was towed into Tuffy Tire & Auto Repair in Appleton, Wisconsin with a failed brake problem. Our technician pulled the vehicle into one of our bays and proceeded to perform a visual inspection. With the vehicle up in the air the gas leak could be found. Next step is to figure out the brake problem. Have to assume it is a rotted out brake line. At Tuffy Tire & Auto Repair we perform custom brake and gas line repairs for most vehicles.
