I began to smell gas near my gas tank. Upon further inspection, I noticed there was gas leaking down the side of the tank. I then tilted my truck bed to look at the leak from above the tank and I noticed that the plastic piece connector coming out of the fuel pump housing to the supply line was pumping a stream of gas all over the top of the tank. I went to disconnect the hose and the plastic piece broke instantly fully cracking apart. Thankfully this was in my driveway and not driving as this would have been very dangerous. There was no warning light and this would have sprayed fuel everywhere, especially at speed. There are hot parts all over there and would probably resulted in a fire, and at the very least the truck to shut off while driving. I did not take it to a dealer as the damage was extremely obvious. The truck has never been in a crash and I’ve never changed out any components involving the fueling system, meaning that it simply broke apart on its own. This appears to be a common problem and yet it is not a recall. I had to spend my own money replacing the fuel pump and housing in the tank, as well as the supply line connector as the plastic on that also failed. I started smelling gas and then a few days later is when I found the issue, but I had been driving the truck, including at highway speeds. The truck has 100,365 miles and I’m the original owner.
My 2015 Chevy Silverado, at 58,600 miles, started having problems with the Fuel Sensor. It wouldn't pick up speed. I had to get the fuel pump sensor changed twice already in January and July of 2024. I am experiencing the same issue again now, and it is now showing an emission code, too. I am only at 69,000 miles. This should be a Recall. There should not be these kinds of issues on a vehicle when it's been fixed for the same issue over and over.
