Cadillac Escalade, Fuel Pump Failure
Q: Is there a way to check a fuel pump failure on a Cadillac Escalade? Our customers mechanic claims our gas caused the failure. However, I have fueled my car out of the same tank and I have had no problems. In fact, I fueled my other car out of same pump that the customer used and I have had no problems with my Ford.

A: I would need to know just what was in the gas that caused the fuel pump to fail? Fuel pump failure is a common occurrence. It can happen in a new vehicle as well as an old vehicle. In an older vehicle it is a little easier to understand, after all the fuel pump has pumped a lot of gas and is just plain worn out. In a new vehicle, it becomes more of a question why. One cause for premature fuel pump failure is dirty gas. Dirt or debris in the gas will cause the fuel pump to wear prematurely and fail. When replacing a fuel pump the technician should always inspect the inside of the gas tank for such debris. If debris is present, the tank has to be cleaned or replaced before the new fuel pump is installed or it will fail again. If youve been selling gas to others from the same pump, I would have to ask why they have not been calling you about fuel pump failures? Also, does this person only buy gas from you? How does the mechanic or the customer know that the so called problem fuel was bought from your fuel pump? Unless, someone can come up with sound answers, Im thinking that the Escalade owner wants someone else to foot the bill for his ride.
