To find your fuel pressure regulator:
1. Identify your engine: Check your vehicle's VIN plate or your owner's manual to determine the engine size (e.g., 4.3L, 5.0L, 5.7L, etc.). This is crucial.
2. Consult a repair manual: A repair manual specific to your year and engine will show you a diagram of the fuel system and the precise location of the fuel pressure regulator. Chilton's and Haynes are popular choices.
3. Look at online diagrams: Search online for "[your engine] 1996 Chevy Silverado fuel system diagram". Many websites offer free diagrams. However, always cross-reference with a reputable repair manual.
Important Note: Working with fuel systems involves potential fire hazards. If you're not comfortable working on your vehicle's fuel system, take it to a qualified mechanic. Improper handling of fuel can be dangerous.
