What Is an E85 Inline Fuel Pump and How Does It Work?
An E85 inline fuel pump is a specific type of fuel pump designed to handle E85 fuel, which consists of 85% ethanol and 15% gasoline. This pump is critical for delivering fuel from the tank to the engine in vehicles compatible with E85.
The U.S. Department of Energy defines an inline fuel pump as a device that moves fuel from the fuel tank to the engine, ensuring adequate fuel pressure and flow. Fuel pumps designed for E85 must withstand the corrosive properties of ethanol.
The E85 inline fuel pump operates by drawing fuel from the tank and pushing it through the fuel lines to the engine. Its components include a motor, impeller, and various seals. These pumps must be specifically designed for high ethanol content to avoid failures.
According to the National Renewable Energy Laboratory, ethanol can degrade traditional fuel pump materials, leading to leaks and inefficiencies. E85 fuel pumps use specialized materials to resist these effects.
The widespread use of E85 fuel can result from increasing consumer interest in alternative fuels, government incentives, and rising gasoline prices. In 2021, E85 sales reached approximately 1 billion gallons in the United States, showing significant growth potential.
The use of E85 fuel pumps can reduce greenhouse gas emissions, promote energy independence, and support local economies by facilitating renewable fuel use.
Health benefits include improved air quality due to lower emissions of certain pollutants. Economically, E85 can reduce consumer dependence on fossil fuels.
Examples of E85 fuel impacts include reduced carbon monoxide emissions and better fuel economy in flex-fuel vehicles.
To address potential challenges in using E85, the Renewable Fuels Association advocates for ongoing research into fuel pump technologies and consumer education on E85 benefits.
Strategies for mitigating issues include investing in compatible infrastructure, incentivizing flex-fuel vehicle production, and expanding public awareness campaigns about E85 as a viable alternative fuel.
Why Is High-Flow Capability Important for E85 Inline Fuel Pumps?
High-flow capability is important for E85 inline fuel pumps because it ensures adequate fuel delivery to high-performance engines. These engines often require more fuel volume than standard gasoline engines. The ability to flow a higher volume of fuel supports proper combustion and optimal engine performance.
The Fuel Systems Lab at the University of Wisconsin-Madison defines high-flow fuel pumps as those that can deliver fuel at rates exceeding standard pump specifications, typically measured in gallons per hour (GPH). This definition is supported by extensive research in automotive fuel delivery systems.
High-flow capability is critical for several reasons. First, E85, which is a blend of 85% ethanol and 15% gasoline, has different properties compared to traditional gasoline. Ethanol has a lower energy density, meaning more fuel is needed to achieve the same power output. Second, high-performance or modified engines often run at higher RPMs, requiring more fuel to maintain stoichiometric air-fuel ratios. Lastly, significant fuel flow is essential for turbocharged or supercharged engines, which demand increased fuel delivery to prevent lean conditions that can damage the engine.
In technical terms, a fuel pump’s flow rate refers to its ability to move a specific volume of fuel within a given time frame. A high-flow pump reduces the risk of fuel starvation during peak power demands. This means that when the engine requires more fuel, such as during acceleration or high-load conditions, the pump can deliver sufficient fuel volume quickly to meet those demands.
Specific conditions that contribute to the need for high-flow capability include modifications to the engine such as increased boost levels in forced-induction setups, camshaft upgrades that enhance airflow, or even larger injectors that necessitate more fuel. For example, in a turbocharged engine, if the boost level is increased without adequate fuel flow, the engine can become lean, leading to knocking or potentially catastrophic engine failure. In such cases, high-flow fuel pumps are essential to maintain engine performance and reliability.

Compatibility with E85:
Compatibility with E85 is crucial when choosing a fuel pump. E85 is a blend of 85% ethanol and 15% gasoline. Ethanol can be corrosive to certain materials, so a pump designed specifically for E85 will prevent premature wear. Not all pumps are suitable for ethanol blends, and using an incompatible pump can lead to failure. -
Flow Rate:
The flow rate defines how much fuel the pump can deliver over time, usually measured in gallons per hour (GPH). A higher flow rate is necessary for performance applications. For daily driving, choose a pump that can handle the fuel demands of your engine. A suitable pump for most daily drivers typically ranges from 255 to 400 GPH. -
Pressure Rating:
The pressure rating indicates the pump’s ability to maintain fuel pressure within the fuel system. E85 engines often require higher pressure for optimal performance. Ensure that the pump can provide at least 40-60 psi for standard applications or higher for performance engines. According to a 2019 study by Fuel Systems Journal, proper pressure is essential for the efficient atomization of fuel and performance. -

How Do You Properly Install and Maintain an E85 Inline Fuel Pump for Optimal Performance?
To properly install and maintain an E85 inline fuel pump for optimal performance, follow these key points: select the right pump, install it correctly, ensure proper wiring, use compatible fuel lines, and conduct regular maintenance.
-
Select the right pump: Choose an E85-compatible pump. E85 is a blend of 85% ethanol and 15% gasoline, which can cause corrosion in non-compatible pumps. Brands like AEM and Walbro offer pumps designed specifically for E85 use.
-
Install it correctly: Ensure the pump is properly mounted and aligned. Follow the manufacturer’s instructions for placement in the fuel system. Typically, the pump should be located close to the fuel tank. This reduces the chances of cavitation, which can occur if the pump is too far from the fuel source.
-
Ensure proper wiring: Connect the pump using the appropriate gauge wiring to handle the electrical load. Refer to the manufacturer’s specifications for wire size. Ensure secure connections to prevent voltage drops that could lower pump efficiency.
-
Use compatible fuel lines: Use fuel lines made from materials resistant to ethanol, such as PTFE or certain rubber compounds. Standard rubber hoses may degrade over time with ethanol exposure.
-
Conduct regular maintenance: Inspect the fuel pump and lines regularly for leaks or wear. Replace the fuel filter at recommended intervals, typically every 10,000 to 15,000 miles. Ethanol can attract moisture, which can lead to corrosion inside the fuel system; consider using a fuel stabilizer designed for E85 to mitigate this risk, especially if the vehicle is stored for long periods.
By adhering to these steps, you can ensure the efficient operation and longevity of your E85 inline fuel pump.
