However, there's no single "fuel pump relay" labeled as such. Instead, you'll find it integrated within the PDC. You'll need to consult your owner's manual or a wiring diagram specific to your 1991 Camaro RS 305 TBI to identify the correct relay. The diagram will show the relay's location within the PDC and what it's labeled as (it might be listed as a "fuel pump" or something similar, or by a number).
Look for a fuse block typically located near the battery, often on the driver's side fender well. The relay itself will be a square or rectangular component that you can pull out once you identify it using the diagram.
