Important Installation & Compatibility Notes

• Pre filter fitment: The included universal pre filter may not fit all vehicle applications.
  Refer to OEM recommendations for proper filter replacement.
• Electrical requirements: Factory fuel pump wiring may not be sufficient to handle the current draw of AEM high flow fuel pumps.
  Refer to the Electrical Requirements section in the instructions document for proper wiring guidance.
  Instructions can be downloaded from the BUY / INSTRUCTIONS tab on AEM product pages.
• Electrical polarity: Ensure the polarity of the electrical plug inside the fuel tank is correct if reused.
  If polarity is incorrect, the connector must be re-pinned or the supplied plug should be used.
• Application sizing: Although AEM high flow fuel pumps share physical dimensions with many OEM fuel pumps,
  they may not be suitable for every application. Always verify fuel pump sizing for your specific vehicle before purchasing.
• No tank modification: AEM does not approve or condone modification of the fuel tank to accommodate a high flow fuel pump
  and cannot guarantee performance or operation if modifications are made.

*Horsepower ratings are based on gasoline use with a base fuel pressure of 43 PSI. Actual power support depends on fuel system configuration,
electrical voltage, and overall system capacity.
