Sierra Fuel Primer Bulb for 1/4 Inch Hose, EPA/CARB Certified, 18-8002EP-1

The Sierra 18-8002EP-1 is a fuel primer bulb built for 1/4 inch fuel hose, used to manually prime the fuel line and carburetor before starting an outboard or other marine engine. The bulb is molded from Fluoroelastomer (FKM), a material chosen for its traditional look and feel while standing up to continuous exposure to gasoline and ethanol-blended fuels. Inside, it uses double check valves with Viton balls and stainless steel springs to control one-way fuel flow as the bulb is squeezed, helping push fuel from the tank to the engine and purge air from the line.

Overall length is 7 1/2 inches (190.5 mm) including the barbed fittings on each end, and the inside diameter of the barbs is sized for 1/4 inch (6.4 mm) fuel hose. The bulb is finished in white and is molded in house, meeting current EPA regulations in effect as of January 1, 2011 for a permeation rate of 15 g/m2/24 hrs, and is both EPA and CARB certified for use in emissions-regulated fuel systems. It is available in standard packs of 12 for shops and installers who need multiple units on hand. This primer bulb is a straightforward replacement part for boaters whose existing 1/4 inch primer bulb has cracked, hardened, or lost its check-valve seal.
