Mercury – Fuel Line Assembly, 12 Ft., 5/16" I.D. | Fuel System | 32-8M0061088

Overview

If you’ve run outboards long enough, you’ve probably chased fuel problems that ended up being nothing more than a worn-out hose or a weak primer bulb. This 12-foot Mercury fuel line assembly is built for the common clip-on setups used on Mercury, Mariner, and Force motors. The hose has a solid, dependable feel—flexible enough to route cleanly, but not the soft, collapsible stuff that starves an engine when you hit the throttle. The primer bulb pumps firm, and the connectors snap in the way they’re supposed to.

Key Features

 • 5/16" Low-Permeation Hose – Helps keep fumes down and fuel fresh.

 • Gray UV-Resistant Jacket – Runs cooler in the sun and helps prevent vapor lock.
 • Clip-On Quick Connects – Correct fittings for both the tank and engine ends.
 • EPA-MERC-PB15 Primer Bulb – Gives a strong, predictable squeeze.

Engine & Boat Compatibility

Performance & Practical Benefits

A fresh line usually straightens out a lot of little fuel complaints—rough idle, hard priming, or the engine sagging when you roll into the throttle. With a proper hose, fuel flow stays steady even when you trim up or bounce through chop. Cold starts get easier, too, because the bulb actually pulls fuel instead of collapsing in your hand.

Why Buy OEM

OEM lines don’t swell, crack, or turn mushy after a season. The connectors lock in cleanly, and the bulb lasts longer than the bargain-bin versions that usually fail right when you need them most. Mercury designs these assemblies to match their fuel system specs, so everything just works.

FAQ

Q1: How do I know the line is going bad?
A: Soft spots, cracked rubber, swelling, fuel smell, or a primer bulb that never gets firm.

Q2: Does bulb direction matter?
A: Yep—make sure the arrow points toward the engine.

Q3: Why are these hoses gray?
A: Gray absorbs less heat than black, helping to reduce vapor lock.

Q4: How often should I replace a fuel line?
A: Most folks check them every season—sun and ethanol wear hoses out faster than expected.

Q5: What does a collapsing hose feel like on the water?
A: The engine bogs, stumbles, or drops off plane because it isn’t getting enough fuel.
