      Description

      Replace The Diaphragm On Your Holley 12-803BF Mechanical Fuel Pressure Regulator. Holley’s mechanical fuel pressure regulators are engineered for lifetime use, designed with a fully serviceable body equipped with an easily replaceable rubber diaphragm. This Fuel Pressure Regulator Diaphragm kit includes a brand new, original Holley Fuel Pressure Regulator Diaphragm for your Holley 12-803BP Fuel Pressure Regulator.

      Restore Lost Performance And Accuracy. Holley Fuel Pressure Regulators are designed to accurately control fuel flow through the carburetor for an efficient, smooth operating engine. To conduct this task, Holley mechanical fuel pressure regulators utilize a durable rubber diaphragm that opens and closes in response to vacuum input, sending the correct amount of fuel to your Engine’s carburetor. Unfortunately, when this diaphragm becomes damaged, it can let excess fuel into the carburetor or leak past the diaphragm into the vacuum lines causing poor performance and an excessively rich running condition. To restore the functionality of your aging Holley fuel pressure to like-new levels of performance, replace the damaged diaphragm with this quality kit.

      Simple Replacement. Replacing this rubber diaphragm is simple, requiring only standard hand tools. Simply remove the associated fuel/vacuum lines, unscrew the four screws at the top, and remove the top plate that sandwiches the diaphragm to the body. At this point, the diaphragm is easily accessible and ready to change.

      Warranty. A 90-day guarantee protects this product from manufacturing defects.

      Application. This Holley Fuel Pressure Regulator Diaphragm is a universal-fit product and a direct replacement for the factory-equipped diaphragm on your Holley 12-803BP mechanical fuel pressure regulator.
