Anyone who's ever been in a pool of water with a dead engine because of a sudden run out of fuel knows the price of energy independence. boat-tank With a volume of 5 liters, it becomes the safety cable that allows you to confidently plan your route without looking at the fuel level indicator, and it's not just a canister with a crane, but an important element of the power system that affects the stability of the power unit and the comfort of navigation.
A standard built-in tank, complete with a motor, often has a limited volume, which is only enough for a short walk or maneuvers in the water. Installing an additional 5 liter capacity allows you to increase the autonomy of the stroke by one and a half to two times, which is critical for fishing or long crossings. In this article, we will discuss in detail the nuances of choice, design features and rules for the operation of such systems.
The modern market offers many solutions, from budget domestic models to famous brands like Mikuni or SeaPro. However, not all containers are equally useful and safe. Wrong choice of material or the lack of the necessary valves can lead not only to engine failure, but also to create an emergency situation on the water, so the issue must be approached with technical literacy.
Design features and materials of manufacture
The basis of any quality tank is the material from which it is made. In the vast majority of cases, a special high-density polyethylene is used for a volume of 5 liters. This material has a unique chemical resistance, does not react with gasoline and oil components, and is also resistant to ultraviolet radiation. Plastic case It does not rust, unlike metal counterparts, and it is easier to tolerate mechanical shocks on the side or pier.
The most important element of the design is the ventilation system and valves. air-valveIt's a system that prevents vacuum from being pumped out, and if the air doesn't come in to replace the gas that's gone, the engine pump can't pump the fuel, and the engine will die, and the quality models have a dual system, one valve for air intake, the other for overpressure release when heated.
⚠️ Warning: Never use homemade bottles or food canisters to make homemade containers. The aggressive components of gasoline can dissolve plastic, leading to leakage and fire.
Special attention should be paid to the neck and the lid mounting system. sealed-lock It eliminates fuel spraying when the boat is rolling or rolling, often the lid is fitted with an oil-resistant rubber sealing gasket that may need to be replaced over time, and visually monitors the fuel level through translucent walls or a built-in scale, allowing for quick assessment of the rest of the course.
Choice Criteria: What to Look at Before Buying
When choosing a 5-litre tank, it is important to consider not only the litre, but also compatibility with your type of outboard motor. The main difference lies in the type of fuel used: two-stroke engines require tanks that allow you to mix gasoline with oil directly in the tank or have a separate compartment, although often mixing occurs in separate containers. fuel-filter In the neck or outlet becomes a priority.
The overall dimensions are also crucial, especially for PVC inflatable boats, where every centimeter of usable space counts. The tank must be stable on the floor of the cockpit or securely attached to the transponder / bank, without taking up space for legs or tackles. Some models have an ergonomic shape that allows them to be installed in narrow niches or under the seats.
When buying, be sure to check the equipment. The standard set usually includes:
- 🛢️ The fuel tank itself with a lid and an air valve.
- 🔌 Fuel hose with fittings for your engine (usually Tohatsu/Yamaha or Suzuki/Mercury).
- 🧹 Pear pump for manual fuel pumping before launch.
- 🔧 A set of adapters for connecting to different types of engines.
Pay attention to the length of the hose. Standard 2-3 meters may not be enough if you plan to install the tank in the bow of the boat, and the motor is on the transom. fuel-tuberesistant to gasoline to avoid wall saturation and loss of elasticity.
Rules of installation and connection to the motor
The proper installation of the remote tank is the key to safe operation. The container should be located strictly horizontally, in a well-ventilated place, away from sources of sparks and open fire. In inflatable boats, the optimal place is a special pocket on the cylinder or space under the seat, if the design allows. The main requirement is to avoid falling overboard or shifting it during sharp maneuvers.
The connection process begins with checking the integrity of all elements of the fuel line. The hose should not have cracks, cracks or swelling. The connection to the motor is through a connector, which must be fixed before clicking or securely pinched, depending on the type of connector. Before starting the engine, be sure to blow the system by pressing on several times. pompuntil it's solid.
☑️ Checking before getting on the water
It is important to follow the direction of the fuel indicated by the arrow on the pump pear. The fuel should flow from the tank to the engine. If you confuse the direction, the gasoline will not go to the engine, and the pear may be damaged. silencer or cylinder block, to avoid melting.
Safety and fuel storage
Gasoline is a flammable liquid, and its vapors are heavier than air, which creates an increased danger in enclosed spaces. Keeping the fuel tank in a sealed rundock or under an awning without ventilation is strictly prohibited. The vapors can accumulate and ignite from the slightest spark, for example, when the starter is turned on or the wiring is closed. Always ensure free access to the tank.
When filling a tank on the shore or a gas station, use a funnel with a mesh filter to eliminate water and mechanical impurities. It is recommended to fill the tank by no more than 90-95%, leaving space for thermal expansion of the fuel. When heated in the sun, the gasoline expands, and if the tank is filled "to the end", the excess will pour through the valve, creating a fire hazard situation.
⚠️ Warning: If you smell gasoline in the boat, stop driving immediately, turn off the engine and ventilate the cockpit.
In the off-season, storage of the tank requires a special approach. Residues of fuel are recommended to be drained, since during prolonged storage, gasoline loses its properties, layers and forms a resinous sediment that clogs the carburetor. Plastic containers are stored in a dark, cool place, away from heating devices and direct sunlight, to prevent the degradation of the material.
Comparative table of popular models
The market offers different options for the production of tanks with a volume of about 5 liters. Below is a comparison of several popular models to help you navigate the range and choose the optimal solution for your boat.
| Model | Materials | Volume (l) | Features |
|---|---|---|---|
| Mikuni 333 | Polyethylene | 6.0 | Built-in filter, universal fitting |
| SeaPro FTB5 | Impact-resistant plastic | 5.5 | Compact shape, reinforced handle |
| Flagman 5L | Plastic. | 5.0 | Budget option, basic equipment |
| Nissan Marine | Special polymer | 6.0 | Original, high chemical resistance |
As you can see from the table, even in the small-volume segment, there are differences in design and configuration. Higher-end models often have built-in filtration systems and more reliable locking mechanisms. Cheap counterparts may require the purchase of pear and hose separately, which will eventually equal the price of finished kits.
Why is it important to buy original pears?
Cheap pears are often made from low-quality rubber that smacks quickly in the cold or softens from gasoline, losing elasticity. Original pears have a return valve of the correct design to prevent the return flow of fuel.
Maintenance and typical faults
Regular maintenance of the fuel system extends the life of not only the tank, but also the engine itself. Periodically inspect the condition of the hose for microcracks, which may not be visible immediately. Rubber pear Over time, it loses elasticity and requires replacement if it stops straightening after compression or begins to pass air.
One of the common problems is clogging of the fuel filter-sludge. If the engine begins to "sneeze" or stall at high speeds, the first thing to check the cleanliness of the mesh in the tank and the transparent glass of the filter (if installed). Dirt, water or paraffin deposits in diesel mixtures (for 4 strokes) can completely block the fuel supply.
- 🧼 Wash the tank with warm water with detergent once a season.
- 🔍 Check the condition of the sealing rings of the cover and fittings.
- 💨 Blow the hose with compressed air during long storage.
Remember, plastic ages over time, and if the tank has been under a heavy impact load or has been under the scorching sun for a long time, its strength may decline, and visual inspection for deformities should become a good habit before each season.
To extend the life of the rubber pear, lubricate it outside with silicone lubricant before long-term storage - this will prevent the walls from sticking together and rubber drying out.
Conclusion and key conclusions
A 5-litre remote tank is a simple but effective solution to enhance your swimming facility, giving you freedom of maneuver and confidence in the future, allowing you to not depend on the vagaries of the built-in fuel supply system. The right choice of model, quality installation and compliance with safety rules will make your exits comfortable and safe.
The main criterion for choosing a tank is not the price, but the availability of safety certificates and the quality of the plastic used, resistant to aggressive environments.
Investing in a good extra tank pays off with the time and nerves you save. Now, knowing all the intricacies, you can choose the device that fits perfectly into your boat and will last for years, and remember that there are no small things on the water, and the reliability of the fuel system is worth paying maximum attention to it.
Frequently Asked Questions (FAQ)
Can I store a tank of gasoline in the garage in winter?
It is highly recommended not to store a tank of gasoline in a residential area or unheated garage, where temperature changes and sparks are possible. Gasoline can change its properties at low temperatures, and vapors create an explosive concentration. It is better to drain the fuel and store the tank empty in a warm room.
Will a 5 liter tank be suitable for a 5 hp engine?
Yes, the tank volume does not depend directly on the power of the engine, but only on your needs for autonomy. The 5 hp engine will work perfectly from the remote tank, the main thing is to ensure the correct connection and sapunization (air access).
How do I know if water has been in the tank?
Water is heavier than gasoline, so it always settles to the bottom. If you see a layer of liquid of a different color in a clear sump or at the bottom of the tank (often cloudy or with sediment), then water has been hit, and you can also see unstable engine operation, sneezing and loss of power.
Can I extend the standard hose?
Technically possible using special gas-resistant hoses and clamps, but motor manufacturers do not recommend making lengths longer than 3-4 meters. The increase in length creates additional resistance, and the fuel pump may not cope with the supply, especially at high revs.
