Quicksilver Fuel Line Assembly 9 ft Gray — 5/16 in Hose with EPA-MERC-PB15 Primer Bulb, Low-Permeation

Quicksilver 8M0061890 is a 9-foot fuel line assembly with a built-in EPA-MERC-PB15 primer bulb designed for Mercury, Mariner and Force outboards.

This ready-to-install fuel hose kit pairs a low-permeation 5/16-inch (8mm) internal diameter line with a durable primer bulb to help you get fuel flowing to your outboard for starting and maintenance tasks. Made to Quicksilver standards for marine use, the assembly resists heat and sunlight exposure better than some generic hoses, and its gray color reduces the chance of vapor lock in warm conditions. Note that quick-disconnect fittings are not included; consult your engine manual for the correct connector type before installation.

How will this fuel line assembly fit my Mercury, Mariner, or Force outboard?

The 8M0061890 uses a universal 5/16 in. (8mm) inner diameter hose that is compatible with many Mercury, Mariner and Force models. Because fittings can vary by year and model, the hose accepts manufacturer-specific quick-disconnect connectors when you install the correct fitting listed in your owner’s manual.

• Inner diameter: 5/16 in. (8mm) low-permeation fuel hose
• Length: 9 feet for flexible routing and reach
• Primer bulb: EPA-MERC-PB15 included for manual priming
• Fittings: not included—use OEM quick-disconnects per manual

Why choose Quicksilver over aftermarket fuel hoses?

Quicksilver is the OEM parts supplier for Mercury Marine and designs parts to match their performance and testing standards. This hose assembly undergoes marine-grade testing to reduce leaks, resist fuel permeation and hold up to UV and heat exposure commonly encountered on boats.

• OEM-level engineering and testing for marine conditions
• Gray hose reduces vapor lock risk versus clear/black alternatives
• Durable, flexible construction for long service life

How do I install and maintain the 9-foot fuel line and primer bulb?

Installation involves cutting the hose to the needed length, attaching the correct quick-disconnect fittings for your engine, and positioning the primer bulb where it can be squeezed easily. Regular checks for cracks, soft spots, or hardening and seasonal replacement if fuel smells or seepage appear will keep the system reliable.

• Trim hose to fit, then install OEM quick-disconnects per engine manual
• Position primer bulb for easy access and ensure correct flow direction
• Inspect periodically for wear, replace if compromised or aged

What performance should I expect from the primer bulb and hose?

The included EPA-MERC-PB15 primer bulb lets you manually draw fuel quickly for starting, bleeding, or maintenance. Combined with the low-permeation hose, you get dependable fuel flow while minimizing vapor loss and degradation from sunlight and heat.

• Quick manual priming to simplify engine starts
• Low-permeation hose reduces fuel vapor escape
• Gray color and flexible build help resist heat-related vapor lock
