The contact owns a 2013 (na) GMC C2500. While driving approximately 55 mph, the contact noticed an abnormal odor in the vehicle. The contact pulled the vehicle into a shopping center and noticed a puddle of fuel under the vehicle. The vehicle was driven to the dealer where it was diagnosed that there was a leak in the fuel line. The fuel line was replaced; however, the failure recurred. The contact mentioned that the fuel line was made out of soybean and the squirrels chewed it, which caused a continuous leak from the fuel line. The manufacturer was notified of the failure. The approximate failure mileage was 31,000.
I have done research on this well known problem of this part creating a wild horse vehicle at unexpected times. So far gm is not helping, the last visit was confirmed this pump was the problem and a new pump was not made and gm only offers a overhauled unit. The current pump is a on going problem with vehicle cuting off and at times turning into a full throttle. Stanadyne the company making the pump is in denial the pump does this. I have talked with other owners with the same problems. I hesitate putting anything used on this vehicle, this problem part is still manufactured new by stanadyn corp. I know for a fact this problem has been brought up repeatedly to gm and national highway safety division. Forget any money for the problem, and the ignorance of this factual problem, I would just like a safe vehicle with out electronic systems that go bad.
