Sierra Teleflex 18-7806-1 Fuel Pump Kit — Direct-Fit Marine Replacement with Complete Pump & Hardware

The Sierra Teleflex 18-7806-1 Fuel Pump Kit is a direct-fit marine replacement designed to restore reliable fuel delivery for high-horsepower outboard and inboard engines.

Built for the tough saltwater and high-vibration conditions of marine service, Sierra parts are engineered to meet or exceed the original equipment they replace. This Teleflex-branded kit includes the essential components to replace a worn or failing mechanical fuel pump, helping maintain steady fuel flow and consistent engine performance. Sierra supplies many OEMs and boatbuilders, so you can expect the kit to match fit, form, and function of the factory part.

What components are included in the Teleflex 18-7806-1 kit?

The kit bundles the primary pump assembly with the common hardware needed for a straightforward swap. Components are selected to replace parts that typically wear during normal marine use so you won’t need to source extra pieces after teardown.

• Complete pump housing and diaphragm assembly for consistent pressure handling
• Gaskets and seals matched to original mating surfaces
• Mounting hardware to align with factory holes and brackets
• O-rings or small fittings to preserve leak-free operation

How does this kit fit my engine and how easy is installation?

Sierra designs replacement parts to mirror OEM dimensions and attachment points, so the Teleflex 18-7806-1 installs with the same fasteners and hoses as the original. Installation difficulty is moderate: a mechanically inclined DIYer can complete the job with basic tools, or a technician can swap it quickly during routine service.

• Direct-fit design minimizes modification or adaptation
• Compatible with the same inlet/outlet routing as factory pump
• Standard hand tools and torque specifications are usually sufficient
• Recommended inspection of fuel lines and clamps during replacement

What performance and durability should I expect from this replacement part?

Constructed for marine environments, the pump kit is made from materials chosen to resist corrosion and mechanical wear under load. While not a performance upgrade, it restores the fuel system to manufacturer-intended operation and helps prevent vapor-lock, fueling interruptions, and irregular idle caused by a failing pump.

• Materials selected for corrosion and vibration resistance
• Diaphragms and seals sized for steady flow at rated rpm ranges
• Meets or exceeds the specifications of the original equipment
• Reduces risk of fuel leaks when installed with proper gaskets

Who is this for: The Sierra Teleflex 18-7806-1 Fuel Pump Kit is aimed at boat owners, marine technicians, and restoration specialists who need an OEM-equivalent replacement for a worn fuel pump. It’s ideal for vessels that demand reliable fuel delivery in saltwater and high-horsepower applications. Choose this kit when you want a like-for-like repair that preserves engine performance and avoids the downtime associated with source hunting parts that may not fit or seal correctly.
