Specifications
The Sierra International 188013EP2 188013EP2 Epa Fuel Line Assembly Mercury is an 8-foot fuel line assembly designed for universal applications, specifically noted for Mercury outboards. It features a prominent, integrated 18-8004EP-1 primer bulb, a crucial component for manual fuel system priming. The tubing itself is constructed from EPA-compliant materials, which are essential for meeting modern emissions standards and ensuring fuel system longevity against degradation.
The 8 ft. length offers ample flexibility for routing the fuel line between the tank and outboard motor, accommodating various boat configurations. The “universal application” claim is supported by standard fuel line fittings that are designed to mate with common outboard fuel tank connectors and engine inlets. The inclusion of the specific 18-8004EP-1 primer bulb is significant; it’s designed for efficient fuel transfer and a solid, responsive feel when squeezed, contributing to reliable engine starting.
Performance & Functionality
This fuel line assembly excels at its primary job: delivering fuel reliably from the tank to the outboard. The EPA-compliant construction ensures it won’t prematurely degrade from ethanol in modern fuels, a common failure point for older fuel lines. The primer bulb is notably effective, allowing for quick and easy priming even after the engine has been sitting for a while, leading to faster starts and less cranking time.
