Where is the fuel pump located on a 1969 Buick Riviera?

On a 1969 Buick Riviera, the fuel pump is located on the engine block, driven by the camshaft. It's not in the tank like many modern cars. You'll find it near the distributor, but its exact position might vary slightly depending on the engine (e.g., 430 vs. 350 cubic inch). A visual inspection or a repair manual specific to your engine size will give you the most accurate location.
