Sierra 18-8005EP-1 Primer Bulb, 3/8 Inch Fuel Line, Replaces 174512

The Sierra 18-8005EP-1 is a 3/8 inch fuel line primer bulb used to manually prime the fuel system on marine engines before startup. Squeezing the bulb draws fuel from the tank through the line and into the engine, purging air from the system so the engine starts more easily. This primer bulb is built with double check valves that use viton balls and stainless steel springs, a valve design intended to hold fuel pressure and resist wear from repeated priming. The bulb body is molded in house as part of Sierra's fuel line assembly program, and it is EPA and CARB certified for marine fuel system use.

The 18-8005EP-1 is designed to work with 3/8 inch ID fuel line and is sold as a standalone component for building or servicing a fuel line assembly, separate from the fuel connector and tank connector fittings used elsewhere in the assembly. It is a direct service replacement for primer bulbs cross-referenced to OEM number 174512.
