NOTE: These kits include a basic filter assembly.  When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump.  In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns.  Again for those applications we'd recommend one of our standard pump applications.

• Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced.  If this is a concern for you checkout our FI-650HP fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.
