2007 Chevrolet Tahoe: fuel pump failure

Filed Jun 24, 2017 · Fuel system · 200,000 miles · AL

The top of the fuel pump rusts out. The fuel tank has a design flaw that holds water around the fuel pump. The fuel pump and fuel lines on top of the tank rust out and causes gas and fumes to escape the tank. Fuel will spray onto exhaust and under the vehicle causing a fire hazard. Also excessive fuel vapors escape the tank. I have researched the problem online and there are numerous complaints to gm of the problem but gm has not addressed the problem. I am not looking for any monetary gain I simply want gm to address the problem before someone is killed. Some people reported the problem before 100,000 miles and nearly all problems occur before 150,000.

My 2007 chevrolet tahoe developed a fuel leak at the discharge of the fuel pump. The leak occurred on the top of the fuel tank directly below the left rear passenger seat. The leak sprayed fuel all over the gas tank and bottom of the truck body. This is a safety concern due to the possibility of the atomized fuel starting on fire. The driver or passengers could have been severely burned. The vehicle was in motion when the leak occurred. I noticed a very strong smell of fuel, I pulled over and gas was dripping off of the fuel tank. The fuel line depressurized after the engine was shut off and continued to spray gas for 10 to 15 seconds.

The top of the poly fuel tank has a recess for the electric fuel pump assembly which is gasket mounted within the tank. The two inch fuel line connectors atop the pump are metal. Due to the design of the poly fuel tank, water can collect within the recess and cause the metal lines to rust-out at the connection bends for the poly fuel lines to engine. The smell of gas starts out as being subtle, however become stronger as the rust pin holes get larger. The gasoline leakage occurs while the vehicle is in operation. This is can be a major safety hazzard if someone throws a smoking butt on the highway. There should be a recall to repair this design

This vehicle is only 8 years old and fuel lines, fuel pump are rusted to the point of failing to support the pressures within the system. Obviously, the type of steel, thickness of fuel line steel material is not made in such manner as to give a reasonable service life before failing. This is a clear failure of an important system within this vehicle that everyone relies on performing to a level of reasonable trust. This failure is only noticeable when you get a gas leak underneath the vehicle, too late and already putting owners at risk of fires or vehicle dying on highway traffic. This leak usually happens very close to the gas tank which is made of plastic, so you only need a source of ignition to cause great damage and / or loss of life. I noticed this fuel leak on the road, when I smelled gas inside the car so I stopped at a gas station to get gas and checked underneath the vehicle and noticed a gas leak coming from what it looked like on top of the gas tank. On further examination, found that the gas leak was coming from the fuel pump supply line connections which were rusted to the point of leaking like a fountain. Installed a new pump and connections only to find other steel lines also rusted and also leaking. Please, this needs to be looked into before some people unaware of these defects pay dearly for some big car maker like gm using inferior materials so they could raise their profit line, regardless of people safety.

The complete fuel system rotted out from under the vehicle almost causing a fire. The fuel tank, fuel pump module, lock ring, fuel lines all had to be replaced and had to do a fuel spill clean up. Luckily, I caught the fuel spill before the cadillac converter warmed up. My mechanic advised me to file a complaint with you because this should have never happened and feels gm should issue a recall due to a safety reasons.
