Exactly where is the fuel pressure regulator

This answer was rated:

''99 Suburban K1500 5.7L
I have looked at Chilton''s manuals, and talked to "people in the know" at the parts stores, and the only answer that I am getting is that it is on the fuel rail. There isn''t a fuel rail. I have spent over an hour digging around my intake looking for something that looks like the parts pictured (3 different styles) and found nothing.

Hello and welcome to Just answer

The fuel pressure regulator is located under the upper air intake plenum mounted to the injector body assembly.

    4. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
