The fuel filter on the Chevrolet Express 3500 van is an important part of the fuel system. Fuel or gasoline must be cleaned as it flows through the fuel lines and into the injectors. The Express has two different fuel filters that clean the fuel from debris and foreign particles.
First Fuel Filter
One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.
Second Fuel Filter Location
The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.
Fuel Filter Types
The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.
Fuel Filter Problems
Once the location and type of the fuel filter is determined in the Express Chevy 3500, you can replace a damaged or clogged filter. Debris and foreign particles build up in both fuel filters and can clog the flow of gasoline in the line. The Express will cough, choke, misfire or not start if the fuel filters are clogged with debris.
