Please check notes in each part listing to ensure the Fuel Pump Relay is correct for your 1988 GMC V1500 SUBURBAN with a 5.7L 350 engine. AIRTEX, STANDARD MOTOR PRODUCTS, & ACDELCO are competing brands, and each brand's Fuel Pump Relay may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Fuel Pump Relay fits only certain 1988 GMC V1500 SUBURBAN models.
Clicking a "More Info" link will display a picture and/or other details about that Fuel Pump Relay in a separate window (you may need to turn off your pop-up-blocking software for this to work).

You may use your browser's Back button or click "Find More Parts" to find more Electrical-Switch & Relay parts, other GMC V1500 SUBURBAN parts or parts for a different vehicle.
