Mercury – 5/16" (8mm) Fuel Line Assembly 12 Feet | Fuel System | Low-Permeation Gray Hose with Primer Bulb | 8M0061896

Overview
If you have ever had a day nearly ruined by a starved engine, you know how important a simple fuel line really is. One soft spot in the hose, one tired primer bulb, and suddenly the motor coughs just as the wind picks up or the fish finally turn on. A solid fuel line assembly is the kind of thing you do not think about when it is right, and cannot ignore when it is wrong. With this Mercury Marine part, you will feel that quiet confidence come back. The 12 foot Mercury 8M0061896 fuel line assembly gives you the reach, flow, and reliability you want, so you can focus on the water instead of worrying about what is happening between the tank and the engine.

Key Features

• Twelve foot fuel line assembly designed to deliver consistent fuel flow from tank to outboard

• Five sixteenth inch (eight millimeter) inside diameter hose sized for common portable and permanent fuel systems

• Integral inline primer bulb provides a firm, positive feel when you are priming before start up

• Supplied as a universal fuel line that can be adapted to many modern fuel systems by adding appropriate connectors

• Low permeation hose construction helps reduce fuel vapor loss and smell

• Gray outer color helps manage heat and lowers the risk of vapor lock in warm conditions

• Durable, flexible hose designed for long service in a harsh marine environment

Engine & Boat Compatibility

• Suitable for many Mercury outboards that require a five sixteenth inch fuel supply line

• Can be adapted to a wide variety of applications by installing the correct engine and tank connectors

• Ideal for boats that need a longer run between tank and engine, such as pontoons and deck boats

• A great option for center consoles and runabouts where the fuel tank sits forward of the transom

• Works well on small fishing rigs, aluminum skiffs, and utility boats that use external tanks and need extra length to route cleanly

Performance & Practical Benefits
You will notice the difference in little moments that matter. The primer bulb on this assembly feels solid in your hand, not mushy or cracked. A few squeezes and you can tell fuel is making its way cleanly through the line. The motor lights more willingly after sitting for a week or a long off season, and you spend less time cranking at the ramp while other boats idle by. Once you are running, that five sixteenth inch inside diameter keeps fuel moving in a smooth, steady stream, which helps the engine respond cleanly when you roll into the throttle.

The extra length of this Mercury Marine part number 8M0061896 gives you more freedom to route the line the right way instead of the only way it will reach. You can avoid tight bends, sharp corners, and awkward stretches that strain fittings. The gray low permeation hose not only holds up against sunlight and heat, it also helps cut down on fuel odor and vapor lock when the boat sits in the sun. The whole system feels more secure, more deliberate, and less like a collection of random pieces thrown together over the years.

Why Buy OEM
Fuel systems are not the place to gamble with mismatched hose and bargain primer bulbs. A genuine Mercury Marine part is built around what marine engines actually need: stable fuel flow, resistance to modern fuel blends, and fittings that will not fight you on installation. The hose composition, wall thickness, and bulb design are all chosen with marine duty in mind, not adapted from lawn equipment or automotive leftovers.

With part number 8M0061896, you are getting a foundation you can trust. Add the correct connectors for your engine and tank, and you have a fuel line assembly that feels purpose built rather than improvised. It is a practical decision that pays off in fewer breakdowns, fewer fuel related mysteries, and more mornings where the engine starts, settles into a smooth idle, and simply does its job.

FAQ

Q1: Which engines does the Mercury 8M0061896 Fuel Line Assembly fit?
This fuel line assembly is designed as a universal five sixteenth inch hose that can be used with many Mercury outboards once the proper engine and tank connectors are installed. If your system specifies a five sixteenth inch supply line, this Mercury Marine part is a strong candidate.

Q2: What makes this different from generic fuel line kits?
The hose and primer bulb are built for marine use, with low permeation construction, a gray heat resistant exterior, and materials that stand up to fuel with ethanol. The design is backed by Mercury Marine engineering rather than generic specifications.

Q3: How do I know if this is the right replacement for my boat?
Check the hose size called out in your owner’s manual or on your existing line. If it is a five sixteenth inch inside diameter and you need about twelve feet of run, part number 8M0061896 will usually be the correct length. You will then match connectors to your engine and tank.

Q4: Can this fuel line be used in both saltwater and freshwater?
Yes. The fuel line assembly is suitable for boats that live in saltwater or freshwater. Just follow normal care for your engine and fuel system, and inspect hoses regularly as part of routine maintenance.

Q5: Is installation straightforward for most boat owners?
Most owners who are comfortable working with clamps and fuel fittings will find it very manageable. Remove the old line, route the new one neatly, install the correct connectors, and ensure everything is tight and secure before priming and starting the engine.
