Removing a gas tank from a fiberglass boat: a step-by-step guide
Before starting, it is important to note that removing a gas tank from a fiberglass boat can be a challenging task and may require multiple people. It is also important to take the necessary safety precautions when working with gasoline and power tools.
First, remove all the gas from the tank. This is an important step to avoid any accidents during the removal process. Once the tank is empty, undo any screws or bolts that are holding the tank in place. If the tank is sealed in with foam, you may need to cut through it with a knife or a crowbar to access the tank. Be cautious when using sharp tools to avoid damaging the boat or injuring yourself.
If the tank is still difficult to remove, you may need to use a tool like a longshoreman's hook or a crowbar to pry it loose. Place a piece of wood or a sturdy object between the tool and the boat to avoid damaging the boat's surface. It may be necessary to rock the tank back and forth to loosen it from its compartment.
For smaller boats, the fuel tank may be foamed in place under the deck. In this case, you will need to remove the console or any other components blocking access to the tank. Getting the foam away from the tank can be challenging. A longshoreman's hook or a similar tool can be used to rip through the foam and create some space around the tank.
Once you have cleared the foam and any other obstructions, you can attempt to lift the tank out. Place two bottle jacks on pieces of plywood on either side of the tank to distribute the load across the deck. Suspend a sturdy piece of wood across the top of the jacks and use a strap, chain, or cable to secure the tank. Ensure that the chain or strap is wrapped tightly around the tank and the jacks are stable before attempting to lift.
Finally, with the tank secured, you can slowly start jacking it up and out of the boat. Be cautious and go slowly to avoid any damage to the boat or injury to yourself. Once the tank is out, clean the compartment and install a new tank.

Tools required to remove a gas tank from a fiberglass boat
Removing a gas tank from a fiberglass boat can be a challenging task and may require a range of tools and equipment. Here is a list of tools that can be useful when removing a gas tank from a fiberglass boat:
- Bottle jacks: Place two bottle jacks on pieces of plywood (about 1 foot square each) to distribute the load across the deck of the boat. Place one jack on each side of the tank, near the end.
- Plywood: Cut plywood into pieces that are about 1 foot square to provide a stable base for the bottle jacks.
- Wood: Suspend a 4" x 4" piece of wood across the top of the jacks to provide a secure anchor point.
- Straps, chains, or cables: Use a heavy-duty strap, chain, or cable to secure the tank. Place it under the end of the tank and wrap each end tightly around the 4 x 4 wood.
- Crowbar: A crowbar can be useful for prying and levering the tank loose.
- Cable: If there is foam under the tank, you may need about 10 feet of 1/8" or 3/16" cable to feed under the tank and cut through the foam.
- Tools for removing screws: Standard tools like screwdrivers or power tools may be needed to undo any screws holding the tank in place.
- Safety equipment: Wear appropriate safety gear, such as gloves and eye protection, to protect yourself during the removal process.
It is important to carefully analyze the situation and consider the specific requirements of your boat before attempting any gas tank removal.

Common issues when removing a gas tank from a fiberglass boat
Removing a gas tank from a fiberglass boat can be a challenging task and is often a neighbourhood project. One of the most common issues faced when removing a gas tank is that it can be difficult to get the tank out, even after removing all the gas and undoing the screws. The tank may be stuck or foamed in on the bottom.
Another common issue is the presence of fumes, which can be dangerous. It is important to take precautions and fill the tank with water and drain it before attempting to remove it. This helps to avoid a potential disaster caused by gas fumes.
In some cases, the gas tank may be glassed in under the deck, requiring the deck to be cut open for access. This can be a difficult and tedious process, as it involves working the tank loose with a crowbar before pulling it out.
Additionally, water leakage can be a common issue when removing a gas tank. Water can leak through the deck or around the fuel fill, puddling on the tank top and, over time, causing rust and allowing water to leak into the tank. This can eventually ruin a boating day by filling the fuel filter.
Furthermore, the use of ethanol-blend gasoline in fiberglass tanks can lead to issues. Ethanol can dissolve the resin that holds the glass fibres together, causing delamination and resulting in costly repairs. While some newer tanks use ethanol-compatible resins, it is generally recommended to restrict fiberglass tanks to diesel fuel or consider alternative tank materials, such as polyethylene or aluminum.

How to dispose of a fiberglass boat's gas tank
To dispose of a fibreglass boat's gas tank, you must first remove it from the boat. This process can be complex and time-consuming, and it may be helpful to have multiple people assisting.
Firstly, remove all the gas from the tank. Then, undo any screws that are holding the tank in place. If the tank is stuck, you may need to use a crowbar to work it loose. If there is foam under the tank, you can use a longshoreman's hook, or a piece of cable, to rip or cut through the foam.
Once the tank is loose, you can use bottle jacks to lift it out. Place two bottle jacks on pieces of plywood that are about 1 foot square each. Position one jack on each side of the tank, near the end, and suspend a 4" x 4" piece of wood across the top of the jacks. Place a strap, chain, or cable under the end of the tank and wrap each end around the 4 x 4, then start jacking. Be careful, as this process may damage the boat.
Once the tank is removed, you can dispose of it. It is important to clean the tank before disposal to remove any fuel residue. To do this, pour about 1 pint of acetone or lacquer thinner into the tank and rotate the tank to thoroughly coat the sides. Dispose of the contaminated solution, then rinse the tank with hot water and dish soap. Rinse again and allow the tank to dry.
Finally, place a handful of drywall screws and about a pint of acetone or lacquer thinner into the tank and shake vigorously to dislodge any remaining particles. Dispose of the contaminated solution and allow the tank to dry. The tank can now be recycled or thrown away according to your local waste management guidelines.

Cleaning a fiberglass boat's gas tank
Cleaning a fibreglass boat's gas tank is a meticulous process that requires careful preparation and execution. Here is a step-by-step guide to help you through the process:
Firstly, safety should be a top priority. Before initiating any cleaning procedures, ensure that the gas line is disconnected. This is crucial as chemicals and motors should never mix. Additionally, make sure the area where you're working is well-ventilated, and always wear protective clothing and gear when dealing with gas.
Next, prepare the tank for cleaning. Drain the tank of any remaining gas or fuel. If the tank contains ethanol-blend gasoline, be cautious as ethanol has a propensity to absorb water, which can lead to corrosion. If there is any oil in the tank, pour in about a pint of acetone or lacquer thinner, and rotate the tank to thoroughly coat the sides with the solvent. However, be mindful that acetone can be aggressive and degrade the fibreglass, so don't leave it in the tank for too long.
Once the tank is empty and prepared, it's time to start cleaning. For a fixed gas tank, angle the boat so that the gas moves to one side. This will help in ensuring that you can access and clean all parts of the tank. You can use a fuel polishing setup, which involves running the fuel from the tank through a filter and back into the tank for several hours. This process helps to remove any particles or sludge that may have built up over time.
After cleaning, it is important to rinse the tank thoroughly. Dump or siphon the cleaning solution into a chemical-safe container and rinse the tank with water. Continue siphoning until the water runs clear, ensuring that all liquid is removed.
Finally, allow the tank to dry completely before reassembling or refilling it. Remember to regularly clean your gas tank to avoid thick sludge and buildup, which can occur if the gas sits in the tank for extended periods.
