Where is the oil pressure sender in a 1980 Chevrolet Corvette?

The oil pressure sender on a 1980 Chevrolet Corvette is located on the front of the engine block, near the oil filter. It's a relatively small unit. You'll likely need to consult a shop manual or a detailed diagram specific to the 1980 Corvette's engine (likely a small-block Chevrolet V8, but it could be a big-block depending on the model) for precise placement. The engine's configuration might slightly alter its exact position.
