Features, Description, Q&A
Replace A Worn Fuel Pressure Regulator Diaphragm. When your fuel pressure regulator begins to exhibit sloppy performance, inaccurate fuel flow, and poor fuel economy, consider replacing the internal diaphragm to enjoy the precision and functionality of the Holley Challenger Fuel Pressure Regulator.
For Use Exclusively With Carbureted Fuel Systems. This fuel pressure regulator is designed exclusively for carbureted fuel systems and is incompatible with modern fuel injection systems. Therefore, in the case of your Challenger, this product can only be used where the electronic fuel injection system has been replaced with a carbureted fuel system in a dedicated race application.Â
Simple Installation. This Holley Fuel Pressure Regulator Diaphragm installs quickly and easily into your Holley 12-803BP fuel pressure regulator. Simply detach the feed and return lines, remove the regulator from the chassis, unscrew the four Phillips head screws at the top of the regulator, and replace the now exposed fuel pressure regulator diaphragm. Then, reinstall all parts in reverse order and enjoy the functionality and efficiency of a brand-new fuel regulator.Â
For Use Exclusively With Holley 12-803BP Fuel Pressure Regulator. This product is designed exclusively to replace the diaphragm of Holley 12-803BP fuel pressure regulators.Â
Warranty. A 90-day limited warranty protects this product from manufacturing defects.Â
Application. This Holley Challenger Fuel Pressure Regulator Diaphragm features a universal fitment applicable to carbureted applications equipped with a Holley 12-803BP fuel pressure regulator.
