Expert Tip: When rebuilding your LPG regulator, take the time to thoroughly clean the inside of the aluminum housing with a high-quality solvent to remove tar and oil buildup before installing your new diaphragms. We highly recommend replacing your primary LP fuel filter at the same time to prevent debris from immediately fouling your fresh rebuild!
