Using a compression fitting with a female NPT thread
To add a barb fitting to a plastic fuel tank, one method is to use a compression fitting with a female NPT thread. This can be achieved by following these steps:
Firstly, it is important to note that the plastic wall of the fuel tank may be too thin to take threads. In this case, a bulkhead fitting can be used. This type of fitting acts like a hollow bolt with internal pipe threads that clamps to the wall of the tank. It is recommended to use a product such as WeatherHead, which offers a bulkhead fitting that can be tightened securely. To ensure a proper seal, Teflon tape should be used, and rubber-type washers should be applied to the fitting head and nut. This will help to create a tight seal and prevent leaks.
When using a compression fitting with a female NPT thread, it is crucial to select the appropriate size and type of fitting for your specific application. Compression fittings are available in various sizes, such as 5/16" or 8mm, so it is important to measure and select the correct size for your fuel tank.
The next step is to prepare the fuel tank for the installation. This may involve drilling a hole in the tank to accommodate the compression fitting. It is important to ensure that the hole is the correct size and is drilled in the appropriate location to avoid any leaks.
Once the fuel tank is prepared, the compression fitting can be installed. This typically involves tightening the fitting into the hole in the fuel tank. It is important to ensure that the fitting is secure and properly sealed to prevent any fuel leaks.
Finally, the barb fitting can be attached to the compression fitting. This will allow for the connection of fuel lines or other components to the fuel tank. Again, it is crucial to ensure that all connections are tight and secure to prevent leaks and ensure the safe operation of the fuel system.
It is worth noting that there are alternative methods to adding a barb fitting to a plastic fuel tank, such as using a grommet or a fuel valve with an O-ring seal. However, the use of a compression fitting with a female NPT thread can be an effective and secure option when performed correctly.

Using a fuel line with a hose clamp
When using a fuel line with a hose clamp, the rubber fuel hose is slipped over the barbed end of the fuel line. A hose clamp is then used to prevent any disconnection. This method is common for low-pressure fuel lines.
For higher-pressure fuel lines, a brass barb fitting can be brazed onto a steel line. Alternatively, a fitting can be flared and then attached to a barb fitting with a coupling. A compression fitting can also be used, although this is not ideal. This fitting can then be attached to a hose barb.
It is important to use proper fuel injection clamps, such as Oetiker clamps, rather than worm gear clamps. The date code on the hose should also be checked to ensure it is recent and compatible with alcohol.
A bubble flare is a common method for transitioning from a fuel line to a rubber hose. This can be achieved using a Mastercool hydraulic flaring tool, which creates a barb-like shape. The hose is then slipped over the flare and double-clamped.
When adding a fuel line to a plastic fuel tank, a bulkhead fitting can be used. This type of fitting clamps to the wall of the tank after insertion and is tightened with a nut. The fitting head and nut should have rubber washers to create a seal. Teflon tape can also be used to seal the fitting.
