Description
The Fuel-It! HPFP upgrade is a direct replacement for your factory high-pressure pump, delivering over 80% more fuel flow capacity. Designed for enthusiasts running heavy E85 blends, it eliminates the need for additional WMI or CPI systems while maintaining reliable, consistent fuel delivery.
This high-performance upgrade is ideal for drivers looking to increase power levels, improve fueling on ethanol blends, and future-proof their setup for advanced modifications.
Key Features:
- Direct factory replacement HPFP with 80%+ increased fuel flow
- Perfect for high-ethanol blends (E50+ capable with tuning)
- Multiple kit configurations available
- Clean, plug-and-play installation with included hardware
- Supports future upgrades such as CANbus integration and low fuel pressure sensor kits
Available Variations:
- HPFP Upgrade Only – Includes HPFP, adapter plate, harness adapter, fuel line, and hardware
- HPFP Upgrade + BMS CANflex Kit – Adds CANflex LED ECA ethanol monitor (digital display + JB4 voltage output, CANbus-ready)

Performance Notes:
- Supports JB4 map5 boost levels (~21psi) on E40 with factory flash
- Capable of 600+ whp on straight E85 with proper tuning
- “Install and forget” reliability compared to CPI systems
- CPI is a lower-cost alternative but requires more installation effort and JB4 tuning
FAQ Highlights:
- Straight E85 Use: Possible with proper tuning adjustments (fuel scalars, AFR mapping, ignition timing, etc.)
- Difference from CPI: CPI is cheaper but more complex to install and tune; HPFP upgrade is simpler and more reliable long-term
