Sierra Siphon Hoses & Fuel Pumps

Sierra Siphon Hoses & Fuel Pumps: Marine-Grade Fuel Delivery You Can Trust

When it comes to keeping fuel flowing safely and reliably aboard your vessel, few names carry as much weight as Sierra. As a leading supplier of aftermarket marine parts for over 35 years, Sierra has built its reputation on engineering components that meet or exceed OEM specifications — and their siphon hoses and fuel pumps are no exception.

Why Fuel Delivery Components Matter on the Water

In a marine environment, the stakes of a fuel system failure are far higher than on land. Managing fuel efficiently and safely is crucial, because the overall design and health of the fuel system directly impact the vessel's performance and safety — encompassing everything from storing fuel effectively to ensuring its purity before it reaches the engine. A compromised siphon hose or a failing fuel pump doesn't just leave you stranded; it can create serious safety hazards on open water.

The delivery of fuel from storage to engine is a critical process. Secure and robust connections are essential to prevent leaks and ensure a consistent fuel supply, and proper installation plus regular checks of all connecting components help maintain the integrity and reliability of the fuel delivery system. Sierra's siphon hoses and fuel pumps are engineered with exactly these demands in mind.

What Sets Sierra Apart in Fuel Pumps

Sierra Marine offers mechanical fuel pumps for a variety of watercraft applications, and these high-quality replacement parts are designed to meet OEM specifications — available in different inlet/outlet sizes and attachments, with most models including a gasket. On the electric side, Sierra's universal electric fuel pumps are designed for use with both gasoline and diesel fuel, with 12-volt models featuring a 72 GPH and 5.75 PSI rating and a 1/4" NPSF thread for 3/8" hose. Sierra also produces fuel pump kits tailored to specific engine platforms — for example, the 18-7823 Fuel Pump Kit is designed for use with Johnson/Evinrude outboard engines and pairs with Sierra's 18-7350 Fuel Pump.

Marine-Grade Hose Construction

Sierra's fuel system hose is designed to handle harsh marine fuel environments , and materials used include corrosion-resistant metals, marine-grade polymers, and ethanol-compatible fuel system components. This is especially important as modern ethanol-blended fuels can degrade standard hose materials over time. When selecting marine fuel hose, it's important to match ratings — choosing USCG-rated hose such as A1-15/B1-15 types for ethanol-blended fuel environments.

Broad Engine Compatibility

Sierra's fuel system components offer wide engine coverage, with popular fits for Mercury/MerCruiser, Yamaha, Johnson/Evinrude, Volvo Penta, Suzuki, Honda, and more. Whether you're performing a routine replacement or restoring a vintage outboard, Sierra's extensive cross-reference catalog makes it straightforward to find the correct part. Backed by an industry-leading warranty, Sierra's aftermarket parts meet or exceed OEM standards — giving boaters confidence that their fuel delivery systems will hold up under real-world marine conditions.
