Edelbrock Fuel Injection Pressure Regulator 1728 FUEL REGULATOR. EST, MON to FRI. Founded in 1938, Torrance-based Edelbrock, LLC is recognized as one of the nation’s premier designers, manufacturers and distributor of performance replacement parts for the automotive aftermarket. Edelbrock produces their core products in the United States of America using state-of-the-art equipment in their world class manufacturing facilities. Edelbrock, LLC encompasses five locations in Southern California and one location in North Carolina totaling more than 500,000 square feet. Edelbrock Corporation has six locations: Three in Torrance California, two in San Jacinto, California, and one in Sanford North Carolina totaling over 500,000 square feet. Torrance Headquarters include: R&D; manufacturing; state-of-the-art testing facilities, advertising and tech support. Less than a mile away is Russell Plumbing and our Distribution Center. Our Aluminum Foundries are located close by in San Jacinto. In 2008 we added a new Permanent Mold and Heat Treat facility next to our existing sand cast foundry, which has been called the most state-of-the-art sand cast foundry west of the Mississippi. This investment in American facilities is part of our commitment to Made in USA products and performance. Edelbrock products start with an original thought or idea that then has to be translated into a working model. Our R&D staff is not only well qualified at their respective positions, but they’re also automotive enthusiasts. Why is being an enthusiast so important? Because an enthusiast does more than work in the automotive aftermarket, they live it – and it’s at that point where understanding the inner workings of a supercharger, or an engine, EFI system becomes second nature. They are constantly thinking of new and innovative ways of making a product that works better.
