Location of fuel pump in 2003 workhorse?

The fuel pump location on a 2003 Workhorse chassis varies depending on the specific engine it's equipped with. Workhorse used several different engines from manufacturers like GM (Chevrolet, GMC) and possibly others.

To find it, you'll need to:

1. Identify your engine: Look for an engine identification tag usually located on the engine itself. This tag will give you the engine's make, model, and displacement (e.g., Vortec 8100).

2. Consult a repair manual: Once you know the engine, find a repair manual specific to your *year, make, and model of Workhorse chassis and that specific engine*. The repair manual will have diagrams showing the fuel system and the exact location of the fuel pump.

3. Look for common locations: While the exact location varies, fuel pumps on most Workhorse chassis with gasoline or diesel engines are typically located in the fuel tank (in-tank pump) or on the frame rail near the fuel tank (external pump). However, using a repair manual is essential for accuracy.

Without knowing the specific engine in your 2003 Workhorse, providing a precise location is impossible. Using the steps above will help you find the correct information.
