Important Notes

• This kit includes a basic filter assembly. Running low on fuel (less than 1/8 tank) during hard acceleration may lead to fuel starvation. For road course applications, consider our standard Stage 2, 3, or 4 pump options to prevent potential issues.
• Upgraded pumps draw more current, so if your EKP (LPFP control module) is weak, it may overheat and need replacement. If this is a concern, check out our FI-650HP fuel pump upgrade kits that retain the stock LPFP while adding a secondary pump.
