Quicksilver Fuel Line

Quicksilver Fuel Line: OEM Engineering for the Marine Fuel System

When it comes to keeping fuel flowing reliably from tank to engine on the open water, few names carry the credibility of Quicksilver. As a brand born directly from Mercury Marine's engineering and manufacturing operation, Quicksilver occupies a unique position in the marine parts market: it is the only aftermarket marine brand manufactured and recommended by an original-equipment manufacturer. That distinction matters enormously when you're choosing something as critical as a fuel line assembly — a component that, if it fails, can leave you stranded far from shore.

Factory-Grade Fuel Line Assemblies Built for the Water

Quicksilver's fuel line lineup centers on complete assemblies and individual components engineered to deliver factory fit and performance for Mercury, Mariner, and Force outboards. Assemblies are available in multiple lengths — including popular 8-foot and 9-foot configurations — with a 5/16-inch (8 mm) inside diameter hose that mates precisely with outboard fuel system specifications. Each assembly can include a pre-installed primer bulb, making it a straightforward, ready-to-run replacement that eliminates guesswork at the dock or on the trailer.

One design detail that sets Quicksilver fuel lines apart is the low-permeation gray hose construction. The gray color is not purely aesthetic — it is specifically chosen to reduce heat absorption in direct sunlight, which in turn lowers the risk of vapor lock on warm, sunny days. For boaters running in shallow, sun-baked bays or logging long hours offshore, that single engineering choice can make the difference between a reliable start and a frustrating afternoon troubleshoot.

A Complete Ecosystem of Fuel Line Components

Beyond full assemblies, Quicksilver offers an ecosystem of individual fuel line components, including quick-disconnect fittings for both the engine end and tank end, designed for 5/16" ID fuel line. The engine-end fittings use a clip-on style quick-disconnect that connects securely and seals reliably, with double-seal designs available to minimize the risk of fuel leakage. These components are compatible with the full range of Mercury and Mariner outboards, as well as select Force models, giving DIY boaters the flexibility to service or upgrade specific sections of their fuel system without replacing the entire assembly.

Quicksilver's approach to materials also acknowledges the reality of today's fuel supply: their fuel line components are engineered to be compatible with current ethanol-blended marine fuels, which can degrade lesser materials and lead to cracking, swelling, or fuel contamination over time.

Why Choose Quicksilver for Your Fuel Line Replacement?

• OEM Pedigree: Quicksilver parts are manufactured by Mercury Marine — the same engineering DNA as factory original components.
• Broad Compatibility: Fuel line assemblies and fittings cover Mercury, Mariner, and Force outboard applications.
• Low-Permeation Construction: Gray hose material reduces heat absorption and helps prevent vapor lock in warm conditions.
• Ethanol-Compatible Materials: Built to hold up against the corrosive effects of ethanol-blended fuels common at modern fuel docks.
• Complete System Coverage: From full assemblies with primer bulbs to individual fittings and connectors, Quicksilver covers every component in the fuel line circuit.

Whether you're doing a seasonal inspection, responding to a cracked hose, or refreshing an aging fuel system before it causes problems, Quicksilver's fuel line products provide the confidence that comes with OEM-level engineering.
