Mercury – Fuel Line Assembly, 12 Ft., 5/16" I.D. | Fuel System | 32-8M0053988

Overview

Pressurized portable tanks can be picky, and a tired fuel line is usually the first thing that makes them act up. This 12-foot Mercury fuel line assembly is made specifically for the 2011-style pressurized 6.6-gallon tank setup. The hose feels sturdy but still bends where you need it, and the primer bulb actually pulls fuel instead of collapsing in your hand. If your engine has been stumbling, losing prime, or acting like it’s running out of fuel halfway across the bay, a fresh line like this often fixes the whole problem in one shot.

Key Features

 • 5/16" (8mm) Fuel Hose – Sized for steady fuel flow to most small and mid-range outboards.
 • Inline Primer Bulb – Gives a firm, predictable squeeze for clean priming.
 • Correct Connectors – Hooks directly to the pigtail on 2011 pressurized 6.6-gallon tanks and the engine end.
 • Durable, Flexible Build – Handles routing around rigging without kinking.
 • Gray UV-Resistant Jacket – Stays cooler in the sun and helps reduce vapor lock.

Engine & Boat Compatibility

 • 2011 pressurized 6.6-gallon portable tanks
 • Fuel systems using Mercury pigtail connectors
 • Outboard engines requiring 5/16" fuel hose
 • Portable tank setups

Performance & Practical Benefits

Replacing an old fuel line usually brings back steady fuel delivery right away. The motor primes faster, idle settles down, and throttle pulls feel cleaner because the hose isn’t collapsing or leaking air. You’ll also notice fewer hiccups when you trim up or bounce through chop. A solid primer bulb and a good hose make a bigger difference than most boaters expect—especially with pressurized tanks.

Why Buy OEM

OEM lines lock in cleanly, seal right the first time, and last longer under sunlight, vibration, and ethanol-blended fuel. Cheap aftermarket hose often gets soft, swells, or leaks around the connectors. Mercury’s assemblies are built around the exact tank and engine fittings, so everything works the way it’s supposed to.

FAQ

Q1: What are early signs the fuel line is worn out?
A: Soft spots, cracking, swelling, fuel odor, or a primer bulb that never firms up.

Q2: Does the primer bulb orientation matter?
A: Yes—keep the arrow pointing toward the engine for proper flow.

Q3: Why is a gray hose better in the heat?
A: It absorbs less heat, helping prevent vapor lock on hot days.

Q4: How often should I inspect or replace the line?
A: Once a season is a good routine—sun, ethanol, and age wear them down faster than people expect.

Q5: What happens if the hose collapses underway?
A: The engine may bog, lose power, or fall off plane due to fuel starvation.
