Unfortunately, pinpointing the *exact* location within that fuse block without a wiring diagram specific to your year and model is difficult. The best approach is:
1. Locate the Underhood Fuse Block: This is usually found near the battery, often on the driver's side fender well. It's a rectangular box with numerous fuses and relays.
2. Consult Your Owner's Manual: This is your best bet. The owner's manual should have a diagram of the fuse block showing the location of the fuel pump relay. The relay may be labeled, or you may find it listed in a legend.
3. Use a Wiring Diagram: A wiring diagram for your specific 1992 Beretta 2.2L is the most definitive source. You can find these online through various automotive repair websites (sometimes for a fee) or at a parts store. This will show the exact relay and its location.
4. Check Online Forums: Search online forums dedicated to Chevrolet Berettas or GM vehicles. Someone may have already posted about the fuel pump relay location for that model year.
Important Note: Working with car electrical systems can be dangerous. If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic.
