Fuel tank catalysts are pellets placed in fuel tanks to improve fuel efficiency and engine performance. They are believed to remove carbon deposits and keep engines clean. The use of tin-antimony alloy pellets in fuel tanks was first discovered by the American motor industry in 1942, when they found that the pellets caused fuels to self-clean upon combustion. Fuel tank catalysts are now used by private and commercial vehicle owners worldwide. However, there is limited scientific literature on the chemical reactions that occur, and some skepticism about their effectiveness.

What You'll Learn
Fuel catalysts for classic vehicles
Fuel catalysts are designed to improve fuel economy and engine performance. They are particularly useful for classic vehicles, which may experience a decline in engine efficiency over time due to deposits forming inside the engine.
One example of a fuel catalyst for classic vehicles is the Fitch Fuel Catalyst, which comes in the form of drop-in cartridges that are lowered into the fuel tank. This product is suitable for pre-1980 classic vehicles with fuel tanks of 35 gallons or less for gasoline engines and 20 gallons or less for diesel engines. It is important to note that vehicles manufactured after 1980 may have an anti-siphon obstruction that prevents the installation of drop-in catalyst cartridges through the fuel filler cap, requiring an alternative installation method.
The Fitch Fuel Catalyst has received positive reviews from consumers, who have reported improvements in fuel economy, engine performance, and reduced emissions. Some users have noted an increase in miles per gallon, smoother idling, improved throttle response, and enhanced acceleration.
Another fuel catalyst option for classic vehicles is the FTC fuel catalyst, which uses tin-antimony alloy pellets to remove carbon deposits and keep engines clean. FTC claims that their product can improve fuel efficiency, engine smoothness, and acceleration while reducing emissions and engine noise. Customer testimonials on the FTC website support these claims, with many users reporting positive experiences and significant improvements in their vehicles' performance.
It is important to note that while fuel catalysts may offer potential benefits, there are also sceptics who question the effectiveness of such products. Some individuals may be hesitant to try fuel catalysts due to the abundance of performance-enhancing products on the market that do not deliver on their promises. Therefore, it is essential to conduct thorough research and consider the specific needs and characteristics of your classic vehicle before investing in any fuel catalyst product.

Fuel catalysts for modern vehicles
Fuel catalysts are designed to improve the combustion process, increasing power and efficiency, and reducing pollutant emissions. They can be used in any application or engine type that uses liquid fuel, including modern vehicles.
Fuel catalysts work by removing carbon deposits that build up inside engines over time. This build-up of deposits occurs in all engines, regardless of the quality of the fuel. These deposits make engines less efficient, and fuel catalysts are designed to remove them and keep engines permanently clean. Fuel additives are also formulated to clean these deposits, but they do not increase fuel efficiency in the same way that fuel catalysts do.
Fuel catalysts can be used in gasoline, diesel, bunker, ethanol, and methanol engines. They are available in tablet form, or as a drop-in tank catalyst, which is dropped directly into the fuel tank.
Some companies that produce fuel catalysts include Rennsli, FFC, FTC, and CDTi. Reviews for these products are generally positive, with customers reporting improved fuel economy and engine performance.

How to install fuel catalysts
Installing a fuel catalyst can be a smart upgrade for vehicles, improving fuel efficiency and performance. It is important to note that the installation process may vary depending on the vehicle and fuel catalyst product. Here is a general step-by-step guide on how to install a fuel catalyst:
Step 1: Prepare the Vehicle
Before beginning the installation, it is crucial to prioritize safety. Gasoline vapors are highly flammable, so it is important to work in a well-ventilated area and avoid any potential sources of ignition. Disconnect the battery to prevent accidental sparks, and relieve the fuel system pressure by loosening the gas cap and depressurizing the system if needed.
Step 2: Access the Fuel System
If your vehicle has a stock fuel tank, it will need to be removed before installing the fuel catalyst. Disconnect and safely drain the fuel lines, filler hoses, and any electrical connectors attached to the sending unit or fuel pump.
Step 3: Install the Fuel Catalyst
Select a mounting location for the fuel catalyst, typically near the fuel pump or fuel filter. Ensure that the catalyst is installed in the correct direction, following the directional-flow arrows. Securely fasten the catalyst using appropriate mounting hardware, such as rubber clamps, steel mounting brackets, or straps.
Step 4: Connect the Fuel Lines
Run the fuel lines from the catalyst to the fuel pump or fuel rail. Use high-quality fuel hoses rated for gasoline or ethanol. Ensure that all connections are secure and properly sealed to prevent leaks.
Step 5: Ventilation and Grounding
Install a proper vent line for the fuel cell to prevent vapor buildup. Use a rollover vent valve and route the hose away from heat sources. Ensure that the vent line has a fuel-safe filter and is designed to prevent kinking or clogging. Verify that the fuel cell is properly grounded to the vehicle chassis, as grounding is critical for both safety and the proper function of the fuel gauge.
Step 6: Final Checks
Once the installation is complete, double-check all connections and ensure that there are no leaks in the fuel system. Reattach any removed components and reconnect the battery. Start the engine and inspect for any unusual noises or issues.
For older vehicles without quick-connect fittings, installing a fuel catalyst may be as simple as dropping the cartridges directly into the fuel tank through the filler line. Always refer to the specific instructions provided by the manufacturer of the fuel catalyst product for detailed installation guidelines.
It is worth noting that some fuel catalysts, like the Fuel Cat, can be dropped directly into the fuel tank, offering a quick and easy installation process.

Fuel catalysts and emissions
Fuel catalysts are metal pellets that are dropped into the fuel tanks of vehicles. They are marketed as a way to improve fuel efficiency and engine performance by removing carbon deposits and keeping engines clean. The idea of using fuel catalysts dates back to World War II when tin-antimony pellets were added to the fuel tanks of fighter planes, allowing them to operate above their usual ceiling.
Since the 1960s, tin-antimony alloy has been used by vehicle owners to keep their engines clean and improve performance. Fuel catalyst products such as FTC (for petrol and diesel engines) and Fitch Fuel Catalysts (for older vehicles) are available for purchase online and have received positive reviews from customers who have noticed improvements in fuel economy and engine performance.
However, there is a lack of scientific literature and explanation from manufacturers about how these fuel catalysts work. Some people are sceptical of their effectiveness, especially since the automotive industry does not include them in new vehicles. It is argued that if these fuel catalysts were truly effective, automakers would include them in vehicles to improve performance and fuel efficiency.
Despite the positive testimonials, there is no clear scientific evidence that fuel catalysts directly impact emissions. While fuel catalysts may improve fuel efficiency and engine performance, this does not necessarily indicate a reduction in emissions. The impact of fuel catalysts on emissions may be indirect, as improved fuel efficiency could lead to reduced fuel consumption and, consequently, lower emissions over time.

Fuel catalysts and fuel economy
Fuel catalysts are devices that are placed in the fuel tank of a vehicle to improve fuel economy and engine performance. They are typically sold in the form of metal pellets or a drop-in cartridge that is placed directly into the fuel tank. The pellets are usually made of a tin-antimony alloy, which has been shown to improve fuel efficiency and engine performance in older vehicles, particularly those manufactured before 1980.
The use of fuel catalysts dates back to World War II when Russian scientists developed tin-antimony pellets for use in the fuel tanks of fighter planes. The pellets were found to improve engine performance and fuel efficiency, allowing the planes to operate above their usual ceiling. Since then, fuel catalysts have been used by private and commercial vehicle owners to improve fuel economy and engine performance, particularly in older vehicles.
The claimed mechanism of action for fuel catalysts is that they aid in the attachment of oxygen molecules to the hydrocarbon molecules in the fuel, allowing it to burn more efficiently. This is said to result in a more complete burn of the fuel and improved fuel economy. However, there is limited scientific literature or empirical evidence to support these claims directly. Most of the evidence for the effectiveness of fuel catalysts comes from customer testimonials and anecdotal evidence.
Some users have reported improved fuel economy and engine performance after using fuel catalysts in their vehicles. For example, one user reported a small improvement in fuel economy of about 1% or a gain of less than 3 miles from the same 3.5 gallons of fuel after using a fuel catalyst. Another user reported that their bike idled more consistently, regardless of whether the engine was hot or cold, and experienced a newfound ability to pull off-idle without the usual small stumble. These improvements suggest that fuel catalysts may have a positive impact on fuel economy and engine performance, particularly in older vehicles.
