2. Flow Rate: Ensure the fuel pump has a sufficient flow rate to handle E85. A pump with a higher flow rate, like a 340lph fuel pump, can provide the necessary fuel delivery for vehicles that require more fuel due to the different combustion characteristics of E85.

3. Compatibility Ratings: Check for compatibility ratings. Some pumps are specifically designed for high-ethanol blends. Look for certifications or manufacturer specifications.

4. Replacement Parts: Consider the availability of replacement parts. Some pumps may not have compatible parts for repairs due to ethanol damage.

5. Pump Design: Opt for in-tank pumps that are more resilient to E85. External pumps might not be able to cope with the unique challenges posed by ethanol.

These steps guide the selection process and ensure your fuel pump can handle the demands of E85, enhancing performance and reducing the risk of failures.

Why Is In-Tank Installation Preferred for Performance Fuel Pumps?

In-tank installation is preferred for performance fuel pumps due to several advantages it offers. This setup ensures efficient cooling and consistent fuel delivery under various conditions.

The Society of Automotive Engineers (SAE) defines a fuel pump as a component that moves fuel from the tank to the engine at the required pressure and volume. Good references for performance fuel pumps can be found from their technical publications and guidelines.

In-tank fuel pumps are advantageous because they operate submerged in the fuel. This setup provides several benefits: it keeps the pump cool, which enhances its performance and lifespan; it leads to reduced noise levels compared to external pumps; and it ensures more stable fuel delivery, crucial for high-performance engines.

The low temperature of submerged fuel acts as a coolant for the pump, preventing overheating. Overheating can lead to pump failure or inefficient performance. Furthermore, in-tank pumps are generally positioned closer to the fuel source, reducing the risk of cavitation. Cavitation occurs when vapor bubbles form in the fuel, which can cause damage to the pump and disrupt fuel flow.

Specific conditions favor the in-tank installation of performance fuel pumps. For example, high-demand racing environments require consistent fuel delivery under extreme circumstances. The pump’s location within the tank protects it from debris and contaminants. In everyday scenarios, vehicles facing varying fuel levels benefit from in-tank pumps because they maintain efficiency even when the tank is not full.

Overall, in-tank installation provides essential cooling, reduces noise, improves performance consistency, and protects the pump from damage, making it the preferred choice for performance fuel pumps.
