The Complete Guide to Buying Boat Gas Tanks

Introduction

If you're planning a day or weekend out on the water, you'll need to make sure you have enough fuel to get you there and back. That's where boat gas tanks come in. Boat gas tanks are essential for ensuring your boat has enough fuel to get you to and from your destination. They come in a variety of shapes and sizes, so it's important to know what to look for when choosing one for your boat.

Considerations

Before purchasing a boat gas tank, there are a few things to consider. The size of the tank is the first and most important factor. Gas tanks come in a variety of sizes, so make sure to measure the space in your boat where you plan to install the tank before purchasing. You'll also want to consider the type of fuel the tank will be using. If you're using a gasoline-powered engine, you'll need a gasoline tank. If you're using a diesel-powered engine, you'll need a diesel tank.

Materials

When it comes to the materials of boat gas tanks, there are two main types: plastic and metal. Plastic tanks are the more popular option and they come in a variety of shapes and sizes. Plastic tanks are lightweight and affordable, but they can be prone to cracking over time. Metal tanks are the more durable option, but they are also heavier and more expensive. It's important to determine which material is best for your boat and your budget.

Safety

Safety is an important factor to consider when choosing a boat gas tank. Make sure to look for tanks that are UL (Underwriters Laboratories) certified as this certification ensures the tanks meet certain safety standards. Additionally, look for tanks that have a corrosion-resistant coating to prevent rust and protect the tank from the elements.

Installation

Once you have the right tank, it's time to install it. Make sure to read the instructions that come with the tank and follow them closely. If you're not comfortable with the installation process, you can always hire a professional to do it for you.

Maintenance

Once the tank is installed, it's important to maintain it properly. Make sure to check the tank regularly for any signs of wear and tear. Additionally, it's important to make sure the fuel is properly filtered and that the tank is properly vented. This will help to ensure the tank is functioning properly and will help to extend the life of the tank.

Conclusion

Choosing a boat gas tank is an important part of your boating experience. Make sure to take your time and consider the size, material, safety, installation, and maintenance of the tank before making your purchase. With the right tank and the proper maintenance, you can ensure that your boat is running efficiently and safely.

Frequently Asked Questions (FAQs)

1. What size are boat fuel tanks?

Boat fuel tanks come in various sizes, ranging from one-gallon to fifty-gallon capacity. Permanent fuel tanks, made of aluminum or plastic, are installed in the boat's hull and can hold ten to several hundred gallons of fuel.

2. Do boats need special gas?

Yes, boats require fuel with no more than 10 percent ethanol (E10). Using fuel with more than 10 percent ethanol, such as E15 or E85, should be avoided in marine engines.

3. How long do plastic marine fuel tanks last?

The average lifespan of a polyethylene fuel tank is around 20 years, depending on factors such as maintenance and usage. However, it is important to note that warranties on storage tanks may vary among manufacturers.

4. What is the most common gas tank size?

For cars, the average fuel tank capacity is 50-60 liters (12-16 US gallons). However, boat fuel tanks come in various sizes depending on the specific needs and requirements of the vessel.

5. Why are boat fuel tanks vented?

Boat fuel tanks are vented to relieve the pressure that builds up while filling the tank. Unlike pressurized fuel tanks in automobiles, boats require an air vent to prevent pressure buildup.

6. Why should a boat's gas tank never be completely filled?

It is important to never fill a boat's gas tank beyond 90% full. This allows room for gas to expand and prevents potential overflow. Additionally, it is important to ensure that all air vents and valves to the gas tank are open and to securely replace the gas cap after fueling.

7. Should I put premium gas in my boat?

The fuel requirements for a boat should be specified in the boat's manual. It is important to follow the recommended minimum fuel octane rating. High-performance engines may require a higher octane rating than the standard 87 octane.

8. What is the problem with plastic fuel tanks?

Plastic fuel tanks may start to deteriorate after 10 to 12 years of service, potentially leading to issues such as flaking off the inside of the tank and clogging the fuel filter. In such cases, replacing the fuel filter and the fuel tank is necessary.

9. Are plastic or metal fuel tanks better?

Steel fuel tanks are less likely to leak excess fuel and are generally heavier than plastic tanks. Plastic tanks are lighter but may be more permeable. The choice between plastic or metal fuel tanks depends on factors such as weight, permeability, and specific requirements.
