Quicksilver Fuel Line Assembly 9 ft Grey with EPA‑MERC‑PB15 Primer Bulb — 5/16in Low‑Permeation, Flexible Marine Hose

Quicksilver 8M0061890 is a 9-foot, low-permeation fuel line assembly with an integrated EPA-MERC-PB15 primer bulb designed to replace or extend fuel delivery on Mercury, Mariner and Force outboards.

This complete product description explains what the assembly contains, why its materials matter for marine use, and how it fits into routine maintenance. The hose is 5/16 in. (8 mm) inside diameter, engineered for reduced vapor permeation and improved flexibility, with a gray finish that helps manage heat exposure. The primer bulb is included to aid fuel priming, but quick-disconnect fittings are not supplied — verify the correct connectors for your engine in the owner's manual before installation.

How will this fuel line assembly improve my outboard's fuel delivery?

The Quicksilver hose reduces fuel vapor permeation compared with generic lines and maintains flexibility for easier routing and installation. The included primer bulb speeds starting by drawing fuel from the tank to the engine, especially after service or when hose length has been changed.

• 5/16 in. (8 mm) inner diameter for standard outboard fuel flow
• Low-permeation material reduces fuel odor and vapor loss
• Primer bulb model EPA-MERC-PB15 included for reliable priming
• Gray color lowers heat absorption and helps prevent vapor lock

Will this hose fit my Mercury, Mariner or Force outboard?

This assembly is made to work with Mercury Marine original-equipment systems, and it is commonly compatible with Mariner and Force outboards as well. Because manufacturers use different quick-disconnect fittings, you should check your owner's manual or existing fittings to confirm the specific connector type before purchasing.

• Designed for Mercury Marine original-equipment compatibility
• Often suitable for Mariner and Force models with matching fittings
• Quick-disconnect connectors are not included — match to your engine
• 9 ft. length provides extra reach for routing and repositioning

How durable and weather-resistant is the Quicksilver fuel hose?

The hose uses marine-grade, flexible compounds chosen to withstand exposure to sunlight, temperature swings, and typical marine fuel blends. The gray outer color helps reduce heat buildup from direct sun, and the construction resists cracking, kinking, and premature wear when installed correctly and inspected regularly.

• Durable, flexible build for long-lasting service life
• Resistant to kinks and everyday wear in marine environments
• Gray color minimizes ultraviolet heat absorption
• Low permeation formula helps reduce chemical degradation effects

What do I need to install and maintain this assembly?

Installation requires the correct quick-disconnect fittings for your engine and basic hand tools. Routine inspection of hose clamps, primer bulb condition, and connections will help maintain safe fuel delivery; replace the hose if you find hardening, cracks, or leaks.

• Confirm and purchase proper quick-disconnect fittings separately
• Use marine-grade clamps and secure routing to prevent chafing
• Inspect primer bulb and hose annually or after any fuel-system work
• Replace at first sign of cracking, leaks, or excessive stiffness

Who is this for: Boaters, marine technicians and DIYers who run Mercury, Mariner or Force outboards and need a reliable 9-foot replacement or extension fuel line with a quality primer bulb. This product suits anyone who values OEM-grade components, reduced vapor permeation, and a hose that’s easier to route and maintain in everyday boating conditions.
