EVIL ENERGY CPE/PTFE LS Swap fuel kit ,Fuel Filter, 6AN Fuel Line & Fittings | 20-120PSI Fuel Pressure Regulator | Fuel Pump

Q: What is included in the EVIL ENERGY LS swap fuel pump kit?
A: Depending on the selected configuration, the kit may include a 300LPH external inline fuel pump, 20FT 6AN CPE, PTFE, or antistatic PTFE hose, a 40-micron inline fuel filter, two 60 mm mounting brackets, a 20–120 PSI adjustable regulator, 6AN hose ends, union fittings, a Y-block splitter, and applicable adapters. Review the selected variant before ordering.

Q: Is this LS swap fuel pump kit vehicle-specific?
A: No. This is a universal-style custom-install kit rather than a vehicle-specific direct-fit package. Confirm the tank outlet, fuel rail, regulator ports, hose routing, fitting sizes, wiring, and mounting space before installation.

Q: What is the published flow rate of the 300LPH inline fuel pump?
A: The published test flow is 300 LPH at 43 PSI and 13.5V. Actual delivery depends on operating pressure, voltage at the pump, wiring, filtration, hose restriction, fittings, regulator setup, and fuel type.

Q: Does the pump deliver 300 LPH at every fuel pressure?
A: No. The 300LPH rating applies to the listed 43 PSI and 13.5V test point. Pump flow normally changes as pressure, voltage, and system restriction change.

Q: Is the included pump suitable for a 12V EFI system?
A: The included unit is a 12V inline fuel pump intended for compatible EFI systems. Verify the required flow, base pressure, fuel type, electrical load, and regulator configuration before use.

Q: Where should the external fuel pump be mounted?
A: Mount the external fuel pump for fuel injection close to the tank and at or below the tank outlet when the vehicle layout permits a safe gravity-fed installation. Keep it away from exhaust heat, moving parts, road debris, and direct impact.

Q: What is the difference between CPE, PTFE, and antistatic PTFE hose?
A: CPE hose offers greater routing flexibility. Standard PTFE hose provides lower fuel permeation and a broader temperature range. Antistatic PTFE includes a conductive inner layer intended for compatible E85, alcohol, or methanol applications.

Q: Which hose option should be selected for E85?
A: Select the antistatic PTFE option for a compatible E85 fuel-system project. The pump, filter, regulator, seals, O-rings, injectors, and fittings must also be verified for E85 compatibility.

Q: How long is the included 6AN fuel hose?
A: The listed CPE, PTFE, and antistatic PTFE hose configurations include 20FT of 6AN hose. Plan the complete feed and return route before cutting the hose.

Q: What does the 40-micron inline fuel filter do?
A: The serviceable 40-micron filter helps capture particles of approximately 40 microns and larger. Its correct position depends on the pump manufacturer’s filtration requirements and the complete fuel-system layout.

Q: Is the 40-micron filter the only filter required?
A: Not necessarily. Some EFI systems require a coarse pre-filter before the pump and a finer post-pump filter before the injectors. Confirm the filtration requirements of the pump, regulator, and injectors.

Q: What is the adjustment range of the fuel pressure regulator?
A: The included regulator has a listed adjustment range of 20–120 PSI. Set the base pressure according to the injectors, fuel rail, engine-management system, and return-style fuel-system requirements.

Q: Does the regulator require a return line?
A: Yes. The fuel pump and pressure regulator configuration is intended for a compatible return-style EFI layout. Confirm that the return line and tank connection can carry excess pump flow.

Q: Which adapters are included with the PTFE kit?
A: The PTFE configurations include M12×1.5 and M18×1.5 adapters with 9/16-18 UNF connections. These adapters are not listed as included with every CPE configuration.

Q: Does the kit include every fitting required for an LS swap?
A: No. The included 6AN fittings, hose ends, unions, adapters, and Y-block support a custom LS fuel pump kit layout, but additional tank, rail, return, gauge, or vehicle-specific fittings may still be required.

Q: What electrical parts are required for the external fuel pump?
A: Use a suitable relay, fuse, power wire, and ground sized for the pump and vehicle electrical system. Verify voltage at the pump while it is operating, because voltage drop can reduce fuel flow.

Q: Can this EFI fuel pump kit support a specific horsepower level?
A: Horsepower support should not be estimated from the 300LPH name alone. Required fuel flow depends on fuel type, engine efficiency, injector duty cycle, boost, base pressure, voltage, and the complete fuel-system design.

Q: What should be checked before ordering?
A: Confirm required EFI pressure, pump flow at that pressure, available pump voltage, hose material, fuel compatibility, filter position, regulator range, return-line capacity, fitting sizes, bracket space, and the exact contents of the selected package.

Q: What should be checked after installation?
A: Prime the system, verify pump voltage and fuel pressure, inspect every hose end and fitting for leaks, and confirm that the lines remain clear of heat, sharp edges, suspension movement, and drivetrain components.

Q: Is professional installation recommended?
A: Professional installation is recommended when custom tank modification, bulkhead fitting installation, EFI pressure setup, return-line plumbing, or fuel-pump wiring is outside the installer’s experience.
