Cost of installation
The cost of installation for a new boat fuel tank varies depending on the size of the tank, the labour rates, and any additional work that needs to be done, such as structural repairs or fuel line replacements. The cost of the tank itself is typically around $10 per gallon, although this can range from $10 to $20 per gallon depending on the local business costs and the size of the tank. For example, one user reported that the price dropped to $10 per gallon for tanks above 50 gallons.

Another user paid $10,000 for two new tanks, including all hoses, fuel lines, and labour. This user noted that the price may have been cheaper if they had not needed the work done so quickly.
Some boat owners choose to replace their fuel tanks themselves to save on labour costs. One user took their old tank to a local welding shop that specialises in boat tanks and had a new one made from heavier gauge aluminium for $960. They then ran new fuel lines and applied two coats of epoxy primer to the tank.

Cost of labour
The cost of labour for replacing a boat fuel tank can vary significantly depending on several factors. These include local labour rates, the complexity of the job, the size and type of the tank, the ease or difficulty of removing the old tank, and any necessary structural repairs or fuel line replacements.
One source suggests that labour for a fuel tank replacement can cost around $3000, bringing the total cost of the project, including the tank, to about $5000. However, this can vary depending on the size of the tank, with larger tanks potentially costing more per gallon. For example, one user reported paying about $10,000 for two new tanks, including labour, hoses, and fuel lines. This was for a 72-gallon and a 134-gallon tank, which is significantly larger than a standard 30-gallon tank.
The cost of labour can also depend on whether the boat owner chooses to do the work themselves or hire a professional. For example, one user reported paying $960 for a custom aluminium tank from a local welding shop, but then completed the installation themselves, including running new fuel lines and applying an epoxy primer. This option can save on labour costs but requires the boat owner to have the necessary skills and equipment to complete the job safely and effectively.
Additionally, the location of the boat and the availability of specialised services can impact the cost of labour. For instance, a user in Maryland reported paying around $10,000 for two new tanks, including labour, while another user in Miami was seeking recommendations for a fuel tank replacement service in their area, indicating that prices may vary regionally.
Overall, while the cost of labour for replacing a boat fuel tank can vary, it is typically one of the most significant expenses associated with the project. Boat owners should carefully consider their options, taking into account factors such as tank size, labour rates, and the complexity of the installation, to make an informed decision that aligns with their budget and specific requirements.

The price of the tank itself will depend on its size, with tanks above 50 gallons costing around $10 per gallon, and smaller tanks ranging from $12 to $20 per gallon.

For example, one boat owner reported paying about $10,000 for two new tanks, all hoses and fuel lines, including labour.
Boat owners can save money by doing some of the work themselves. For example, one owner reported taking their old tank to a local welding shop to have a new one made from heavier gauge aluminium, which cost them $960. They then ran new fuel lines and applied two coats of epoxy primer to the tank.
When replacing a boat fuel tank, it is important to consider all the associated costs, including the tank itself, labour, and any necessary repairs or replacements. By researching and comparing prices, boat owners can make informed decisions and find the best value for their money.
