   The failure is believed to have originated in the fuel delivery system, specifically the check valve in the low-pressure fuel feed jumper line at the engine. This valve failed to seat properly, allowing high-pressure pulses to travel back into the low-pressure side of the system. This malfunction caused the S-shaped portion of the fuel feed line near the tank to vibrate excessively against its mounting clip. This constant friction wore through the line, resulting in an…

   Vehicle cranked longer than usual, noticed slight smell of fuel. After arriving home noticed fuel smell was very strong and a puddle of raw fuel under vehicle.

    I was constantly smelling a strong odor of gas coming from the inside/outside of my 2015 Chevy Tahoe. When I purchased the vehicle in 10/23 everything appeared fine. I researched the internet to determine what the problem could be & found dozens of similar situations. People saying the fuel line rubs the undercarriage of the vehicle causing a pin hole size in the fuel line causing it to leak gas. Currently my vehicle is in the shop and the problem is TBD.
