Fuel Tank & Fuel Cell Bulkhead Fittings

What Is a Bulkhead on a Fuel Tank?

A bulkhead on a fuel tank is a specialized fitting that serves as a connection point for various fuel-related components in a secure and sealed manner. It is typically used in fuel cell installations and racing applications where precise fuel delivery and containment are crucial.

The bulkhead fitting consists of two main components: an outer threaded sleeve and an inner fitting. The outer sleeve is installed through a hole in the fuel cell or tank wall, creating a sealed passage. The inner fitting connects to the outer sleeve on both sides of the wall, allowing for the secure attachment of fuel lines, hoses, or other components. This design prevents fuel leaks and ensures the safety and performance of the fuel system.

How Do You Size a Bulkhead Fitting?

Sizing a bulkhead fitting correctly is essential to ensure a proper fit and seal in your fuel system. Here are the steps to determine the appropriate size for your bulkhead fitting:

1. Measure the diameter of the fuel line or hose that will be connected to the bulkhead fitting.
2. Choose a bulkhead fitting with threads that match the size of the fuel line or hose. The fitting should have the same inner diameter to create a snug fit.
3. Consider the material of the bulkhead fitting. They are commonly available in materials like aluminum, steel, or brass. Select a material suitable for your specific application and fuel type.
4. Ensure that the bulkhead fitting is compatible with the thickness of the fuel cell or tank wall where it will be installed. Some fittings are designed for specific wall thicknesses, so check the product specifications.

How Much Does a Bulkhead Fitting Cost?

The cost of a bulkhead fitting can vary depending on factors such as size, material, and brand. Generally, bulkhead fittings are available in a wide price range to accommodate different budgets. Here's a rough cost estimate:

• Standard Bulkhead Fittings: Basic bulkhead fittings typically start at around $10 to $20 each for smaller sizes and can go up to $50 or more for larger sizes.
• High-Performance or Specialty Fittings: If you require specialized bulkhead fittings for specific racing or performance applications, prices can range from $30 to $100 or more per fitting.

Keep in mind that you may need multiple bulkhead fittings for your fuel system setup, so it's essential to calculate the total cost based on your requirements. Quality and precision are crucial when it comes to fuel system components, so investing in reliable fittings is recommended.
