Diesel leaking from under passenger back wheel

Diesel leaking from under passenger back wheel
Hi, welcome to Just Answer. My name is***** fuel filler is located on that side of the car. Most of the time the leak is caused by an improperly fitted fuel cap. I'd check the cap first and see if it is sealing properly. If the cap is okay the problem will likely be a ruptured fuel hose at the tank.Let me know if you have any questions. Please remember to rate my service in order for the website to credit me for taking your question.Marty

Okay, you have a fuel level sensor and some fuel lines on that side of the car. The level sensor will tend to only leak with more than 3/4 fuel in the tank. If this is a constant leak I'd suspect a fuel line has ruptured.Let me know if you have any questions.Marty
