Fuel Pressure Regulator Diaphragm Repair Kit for 12-803 and 12-804 Regulators
The Holley 12-807 is a diaphragm repair kit for Holley 12-803 and 12-804 carbureted fuel pressure regulators. It includes a replacement diaphragm plus both low- and high-pressure springs, restoring accurate pressure control to a regulator that has developed a torn diaphragm or drifting pressure -- far cheaper than replacing the whole regulator.

Regulate Fuel System Pressure with Ease
