Fuel tank baffles are a solution to the problem of fuel slosh, which can cause fuel starvation and loss of power. Baffles are designed to keep the fuel in the lowest part of the tank, ensuring the fuel pump is constantly pumping fuel to the engine. This is particularly important for vehicles converted to EFI, which require consistent fuel pressure. The design and placement of baffles are crucial to their effectiveness, and companies like Rick's Tanks and Aeromotive offer products and expertise in this area. Aeromotive's Phantom Bladder Baffle, for example, is designed to increase fuel flow and prevent fuel escape during hard acceleration and cornering.

Fuel Tank Baffles prevent fuel starvation
Fuel tank baffles are a solution to fuel starvation issues in vehicles. Fuel starvation occurs when the fuel pump is not constantly pumping fuel to the engine, which can happen when the fuel is pulled away from the pickup point during acceleration or hard cornering. This can cause a loss of power or even a complete shutdown in EFI systems, as they require consistent fuel pressure.
Baffles are installed inside the fuel tank to keep the pickup point for the fuel pump submerged in fuel at all times. By keeping the fuel in the lowest part of the tank, the baffles ensure that the pump is always able to draw fuel, even during hard turns or acceleration. This prevents fuel starvation and maintains consistent fuel pressure.
The location of the baffles within the tank is crucial to their effectiveness. If the baffles are not in the proper location, they may not be able to control fuel slosh effectively. For example, if the fuel pump is mounted at the front corner of the tank, right turns can pull the fuel away from the pump, resulting in fuel starvation. Therefore, it is important to consider the driving style and usage of the vehicle when determining the placement of the baffles.
In addition to their function, fuel tank baffles can also vary in design. For instance, the Phantom Bladder Baffle by Aeromotive utilizes flow control technology to allow a large volume of fuel to flow into the baffle while also preventing fuel escape during hard acceleration, cornering, and off-angle vehicle maneuvers. This design ensures rapid fuel recovery from the surrounding tank, maintaining a consistent fuel supply.
Overall, fuel tank baffles are an essential component in preventing fuel starvation and ensuring optimal vehicle performance. By keeping the fuel pump submerged and maintaining fuel pressure, baffles help to avoid power loss and engine shutdown. Proper baffle placement and design are key factors in achieving these benefits and ensuring a smooth driving experience.

Baffle placement is key to controlling fuel slosh
Fuel slosh is a common issue for vehicles that have been converted to EFI. It occurs when fuel is pulled away from the pickup point during acceleration or hard cornering, causing the pump to pull in air, which can lead to a loss of power or even a complete shutdown in an EFI system due to the consistent fuel pressure requirement. To address this issue, fuel tank baffles are used to keep the fuel in the lowest part of the tank, ensuring that the pickup point for the fuel pump remains submerged in fuel.
The placement of the baffles is critical to their effectiveness in controlling fuel slosh. In the case of Rick's Tanks, the problem was not the absence of baffles but rather their improper location. The fuel pump had been mounted at the front corner of the tank, which caused fuel starvation during right turns when the fuel was pulled away from the pump. This highlights the importance of considering the driving style and intended use of the vehicle when determining the placement of baffles.
For drag racing, a fuel cell can be an effective solution to control fuel slosh, but it may not be practical for regular drivers due to the loss of trunk space and reduced fuel volume. In contrast, a baffled tank offers a more versatile option, allowing for both street use and occasional racetrack driving. The key to successful baffle placement is to keep as much fuel as possible in the lowest part of the tank and to position the pump where fuel slosh will be minimal.
The design of the baffles plays a crucial role in their effectiveness. They need to be designed to keep the fuel in a specific area of the tank, typically the lowest part. This ensures that the fuel pump constantly pumps fuel to the engine, maintaining consistent fuel pressure. Additionally, the size of the baffled area for the fuel pump is important. A smaller baffled area can help control fuel slosh, as seen in Rick's fuel tanks, where the baffled area is much smaller compared to the previous tank.
Overall, baffle placement is indeed key to controlling fuel slosh. By considering the driving style, intended use, and proper baffle design, fuel slosh can be effectively managed, ensuring optimal performance and preventing fuel starvation issues.

Fuel pump positioning impacts performance
Fuel tank baffles are used to control fuel slosh, which is the movement of fuel inside a tank. Baffles keep the fuel pickup point submerged, ensuring the fuel pump constantly pumps fuel to the engine. The positioning of the fuel pump is critical to its effectiveness.
The optimal position for a fuel pump is one that minimizes fuel slosh. This is usually at the lowest part of the tank, where baffles help keep the pickup point submerged. The location of the baffles is crucial, as they need to be designed to keep the fuel in a specific area of the tank.
For electric fuel pumps, such as the Holley electric pump, mounting close to the tank outlet is preferable. This ensures adequate fuel pressure and volume. However, accessibility is also important, and some users opt to mount the pump in the engine bay for easy access to plumbing and electrical connections.
In the case of BMWs, the fuel pump is responsible for pumping fuel from the tank to the carburetor, where it mixes with air to create the optimal fuel-to-air ratio for smooth engine operation. A clogged fuel pump can negatively impact performance, causing a reduction in gas mileage and difficulty starting the engine.

Baffles keep the fuel pickup point submerged
Fuel tank baffles are used to prevent fuel starvation issues caused by fuel slosh during acceleration, deceleration, or hard cornering. Fuel slosh occurs when the fuel moves away from the pickup point of the fuel pump, causing the pump to draw air instead of fuel, which can lead to a loss of power or even a complete shutdown in EFI systems.
Baffles are designed to keep the fuel pickup point submerged in fuel at all times, ensuring a constant supply of fuel to the engine. By keeping the fuel in the lowest part of the tank, the baffles prevent the fuel from being pulled away from the pickup point during acceleration, deceleration, or cornering. This is especially important in EFI systems, which require consistent fuel pressure for proper functioning.
The placement of the baffles is crucial to their effectiveness. If the baffles are not in the proper location, fuel starvation issues can still occur. For example, if the fuel pump is mounted in the front corner of the tank, right turns can pull the fuel away from the pump, resulting in fuel starvation. Therefore, it is important to consider the driving style and usage of the vehicle when determining the placement of the baffles.
In some cases, a fuel cell with a smaller baffled area may be used to control fuel slosh, but this can compromise fuel volume and trunk space, making it less ideal for regular drivers. For vehicles that undergo drag racing or road racing, the location and installation of baffles must be carefully considered to ensure optimal performance.
Overall, baffles play a critical role in maintaining proper fuel delivery by keeping the fuel pickup point submerged. This, in turn, ensures consistent fuel pressure and prevents fuel starvation issues, enhancing the overall performance and reliability of the vehicle.
