Brand: Wilwood Engineering
This cap has a built-in float that alerts you if your brake fluid level is dangerously low. When the fluid level (and the float) drops, an internal switch makes an electrical connection to turn on a warning light on your dash (not included).
Black nylon screw-on type cap fits Wilwood 7 oz, 10 oz, and 10.7 oz plastic reservoirs (not included). The switch turns on when the float drops to 2.7 inches below the top of the reservoir neck. Two shielded male spade terminals in the top of the cap make connection easy. Includes inner cap gasket.
Does not fit Wilwood billet aluminum or 4 oz plastic reservoirs. Does not fit Tilton reservoirs.
