What You'll Learn

Fuel line sizes and types
When it comes to fuel line sizes, there are a few factors to consider. Firstly, the size of the fuel line diameter can depend on the type of fuel used. For example, when using ethanol, a 30% larger fuel line than gasoline is recommended, while methanol requires double the fuel line size. The return lines, which are the fuel lines after the regulator, can generally be one size smaller than the feed line.
Additionally, the size of the engine and the type of car play a role in determining the fuel line size. Smaller-engined older cars with carburettors may use a 6mm hose, while larger-engined cars can use a 10mm hose. Fuel-injected cars can have 12mm or 15mm hoses from the tank to the pump. These sizes refer to the internal diameter of the hose.
The type of fittings and threads is another important consideration. The most common type of fittings is JIC/AN, which are sized based on a combination of thread size and hose size. Hose sizes for JIC/AN fittings include 6mm, 8mm, 10mm, 12mm, 15mm, and 19mm internal diameters. BSP fittings are also available in 1/4" (13mm), 3/8" (15mm), and 1/2" (19mm) sizes.
The type of hose used is also important. Push-on hoses are cost-effective and can be secured with hose clips or swaging, but they are not recommended for in-car use. Teflon/PTFE-lined hoses can be used inside and outside the car as they prevent fuel vapour escape, eliminating stale fuel odours. These hoses have a small outside diameter relative to their bore size, making them suitable for tight installations.

Fuel hose safety
Fuel Hose Selection:
When selecting a fuel hose, it is essential to choose a product that meets the required specifications and standards. For example, in the maritime industry, the International Convention for the Safety of Life at Sea (SOLAS) regulation enforces minimum safety standards, including those for fuel hoses. Choose a fuel hose that is specifically designed for your application, taking into account factors such as temperature and pressure ratings.
Hose Material and Construction:
The material and construction of the fuel hose play a crucial role in its safety. Modern fuel hoses, such as the Wärtsilä Smart fuel hose, are designed with multiple layers, using state-of-the-art rubber material strengthened by embedded steel wires. This construction provides enhanced durability and helps prevent fuel leaks. Additionally, look for hoses with a minimum burst pressure well above the nominal fuel pressure of your system to ensure safety.
Leak Detection and Prevention:
Leak detection systems are vital components of fuel hose safety. The Wärtsilä Smart fuel hose, for instance, features a cutting-edge leakage detection mechanism between its two layers, allowing for constant monitoring and maintenance. This technology helps identify leaks before they become a safety hazard. Additionally, consider using barriers that prevent fuel leakages from spreading to hot surfaces, further reducing the risk of fires.
Breakaway Couplings:
Utilizing safety breakaway couplings is essential for protecting your fuel hose assemblies and loading arms from excessive loads. These couplings are designed with breaking bolts or integrated shut-off valves that activate when subjected to tensile forces. They help prevent hose assemblies from being damaged by excessive tension or angular forces during operation. Breakaway couplings are available with different working pressure and temperature ranges to suit your specific application.
Hose Securing and Protection:
Properly securing and protecting your fuel hose is crucial. Ensure that the hose is securely fastened and cannot move or rub against other components. Protect the hose from heat sources to prevent degradation and potential leaks. Regularly inspect the hose for any signs of wear, abrasion, or damage that could compromise its integrity.
By following these guidelines and staying vigilant about fuel hose safety, you can significantly reduce the risks associated with fuel systems. Remember to consult experts and manufacturers' recommendations for specific advice pertaining to your application.

Fuel cell grounding
Fuel cells are used as an alternative fuel storage option when the factory gas tank is no longer functional, or when additional fuel capacity is required. They can also be used for safety reasons, as they are often lighter than traditional fuel tanks. Fuel cells come in three varieties: hard plastic, aluminium, or bladder-type.
Fuel cells should be grounded to the frame to prevent the buildup of static electricity due to the fuel sloshing within the cell. This buildup could potentially lead to a fuel explosion. To eliminate static charges, metal parts can be bonded together, and a single grounding electrode can be used.
In the case of hydrogen fuel cells, all components must be connected to an electrode of no more than 25 ohms to the ground. This can be achieved by connecting to the building riser loop, which is bonded to the building's steel structure. However, it is important to ensure that the ground quality meets the required standard.
It is worth noting that if all components are connected via metallic piping, additional grounding connections may not be necessary unless we are considering the output of the fuel cell system, which would require grounding per 250.30.

Fuel cell installation
Fuel cells come in three basic varieties: hard plastic, aluminium, or bladder-type. Bladder-type cells are often used in race vehicles as they can absorb the energy of impact or violent movements. Mounting should take into account the movement and chassis flexing that is inherent in an off-road vehicle.
Before installing a fuel cell, you will want to protect it from any sharp elements that could rub against it while driving, such as rivet heads and sheet metal edges. It is also important to ground the fuel cell to the frame to prevent the buildup of static electricity due to the fuel sloshing within the foam, which could lead to a fuel explosion.
When installing a fuel cell, it is important to mark the fittings for the vent and return lines. The vent line should be installed first, followed by the return line. It is also important to check that the hoses are not kinked or blocked, as this can affect the performance of the fuel cell.
If your fuel cell cover panel isn't notched for the rear bulkhead mount, you can use a hacksaw and some sheet metal shears to notch it. This will make it easier to access the fuel cell without having to undo the rear bulkhead bolts.
When disconnecting the fuel lines, it is recommended to use a -6 AN wrench to loosen the closeout plate bolts. It is also important to check the hoses for any cracks or damage and replace them if necessary.
Finally, when installing the new pump, it is important to follow the manufacturer's instructions and torque the bolts to the recommended specification. Over-tightening the bolts can strip them and ruin the fuel cell.

Fuel cell maintenance
Fuel cells are a great alternative to your factory gas tank, providing safe fuel storage, lighter weight, and increased traveling capacity. They come in three varieties: hard plastic, aluminium, and bladder-type cells. Bladder-type cells are often used in race vehicles as they can absorb the energy of impact and violent movements.
- Inspection: Keep an eye out for any signs of fuel dripping on the bottom of the vehicle, as this could indicate a leak. Remember that fuel can travel a long way before finding an exit point, so the source of the leak may not be immediately obvious.
- Preventing Damage: Before removing the fuel cell, loosen the clamps and let the rubber relax. This will make the removal process easier and prevent damage to the rubber seals.
- Warmth: Cold fuel cells are stiff and more difficult to work with. Try to work with warm fuel cells, perhaps by letting the vehicle sit in the sun for a while or keeping the cell in a warm room. Be cautious when using heaters or blow dryers, as they can be an ignition source.
- Safety: When dealing with fuel leaks, be aware that vapors in a defueled aircraft are more combustible than a fully fueled one. Always ensure the hangar is well-ventilated to prevent the buildup of flammable vapors.
- Protection: Tape the edges of openings with fuel cell tape to prevent damage to the cell and protect yourself from sharp metal edges.
- Installation: Familiarize yourself with the installation process by reading the maintenance manual before beginning. This will help ensure the cell is installed correctly and prevent future issues, such as leaks.
- Cleaning: Before packing a fuel cell for shipment, wipe away any residual fuel from the cell to avoid any safety hazards during transport.
- Periodic Checks: Periodically inspect the cell to ensure the seals, gaskets, and check valve are in good condition. Clean or replace the pickup screen that filters out debris in the tank as needed.
