Fuel Pumps for Chevrolet Express 3500
The fuel pump delivers gas to your vehicle’s engine, making it an essential component. A broken fuel pump can disable your Chevrolet Express 3500 and leave you stuck on the side of the road. Diagnosing and replacing failing fuel pumps for Chevrolet Express 3500 is thus essential in preventing an engine breakdown.
What causes a Chevrolet fuel pump to fail?There are several common reasons for your fuel pump to fail or become unreliable, including:
- Loss of power: Because fuel pumps use electricity to operate, damaged or faulty wiring can cause a pump to fail. It is important to rule this possibility out before replacing a fuel pump since the fix for the problem may involve rewiring its connections.
- Dirt: Any debris that gets into your vehicle’s fuel tank will clog the fuel pump and potentially damage it. For this reason, it is important to prevent anything other than fuel from getting into the tank.
- Rust: Like dirt, rust that develops inside your vehicle’s gas tank can flake off and clog the fuel pump. In older vans, it is important to keep the gas tank full to minimize the condensation that leads to corrosion.
- Wear and tear: Like any part of your van, the fuel pump will fail after a long life due to corrosion and wear. Driving excessively with a low gas tank may contribute to wear and tear, although any pump will fail at some point in a vehicle’s life.
The most common way to choose the correct fuel pump for the Express is to find the OEM part number and use this data to match third-party pumps made to fit your vehicle. If you are unable to locate the OEM part number, you can also consult your dealer with your Chevy’s VIN. They will be able to give you the OEM part number.
How do you replace a Chevrolet Express fuel pump?The pump is in your van’s gas tank, so replacing it requires removal of the tank. This replacement can take some time since it needs an empty gas tank. However, if you are an experienced auto technician, replacing the pump could take only one or two hours. If you have little or no experience with this kind of repair work, it may be appropriate to consider taking the van to a repair shop.
