EVIL ENERGY EFI 255LPH Electric Intank Fuel Pump – Budget Pick
Brand: EVIL ENERGY
A cost-effective pump for gasoline EFI systems with moderate power goals.
The EVIL ENERGY EFI 255LPH pump is a budget-friendly option for gasoline EFI systems. It delivers 255 liters per hour at 43 PSI and can handle up to 90 PSI, making it suitable for many mild to moderate performance builds. The pump is designed for 12V DC systems only, so you’ll need a regulator to set final pressure.
Note that the diameter may differ from your original pump, but it should still fit. Using high-impurity fuel can shorten its lifespan, so stick with clean gasoline. This pump is a straightforward choice if you need reliable flow without breaking the bank.
- High flow at 255 LPH
- Operates up to 90 PSI
- Affordable price point
- Not for carbureted systems
