EVIL ENERGY EFI 255LPH Electric In-Tank Fuel Pump — 12V, 43 PSI High-Flow

EVIL ENERGY EFI 255LPH Electric Intank Fuel Pump Kit is a high-flow 12V in-tank gasoline pump engineered to deliver up to 255 liters per hour at 43 PSI for reliable EFI fuel supply.

This compact intank assembly offers boosted fuel flow for performance and modified applications while remaining compatible with standard 12V electronic fuel injection (EFI) systems. It’s built for gasoline use only and works across a wide operating pressure range; final system pressure is controlled by your regulator. Because the housing may differ from OE dimensions, some installations require updated hoses, filters, or fittings, and professional installation is recommended to ensure fit and safe operation.

How much flow and pressure can I expect from this pump?

The EVIL ENERGY EFI 255LPH is rated for multiple test points: it produces approximately 255 LPH at 43 PSI and around 190 LPH at 80 PSI. The pump functions across an operating pressure window of roughly 15–90 PSI; your system’s regulator determines the final operating pressure.

• Peak test flow: 255 liters per hour at 43 PSI
• Alternate test point: ~190 LPH at 80 PSI
• Working pressure range: 15–90 PSI (set via regulator)
• Final system pressure requires a compatible fuel pressure regulator

Will this pump fit my vehicle and fuel system?

This unit is designed specifically for 12V EFI systems and for gasoline use only. The physical diameter of the 255LPH intank version may differ from original equipment, so tank adapters or replacement hoses and filters might be necessary for correct fitment.

• Designed for 12V DC EFI applications
• Gasoline-only compatibility—do not use with diesel or alcohol blends
• May require tank hardware, hose, or filter replacement due to diameter differences
• Professional installation advised to confirm fit and safety

What should I know about durability and fuel quality?

The pump is optimised for stable, efficient gasoline delivery, but contaminants and high-impurity fuel can shorten service life and impair performance. Routine fuel filtration and using clean, compatible gasoline will help preserve pump reliability.

• Best used with clean, low-contaminant gasoline
• High-impurity fuel may reduce lifespan and performance
• Install a quality in-line or tank filter if not already present
• Regular inspection and maintenance recommended for longevity

How should I install and integrate this pump into my EFI system?

Because the pump’s form factor might not match OE dimensions, plan for potential modifications such as new hoses, clamps, or an adaptor plate. Verify electrical connections, use proper fuel-rated fittings, and set system pressure with a compatible regulator after installation.

• Confirm 12V electrical compatibility and secure wiring
• Replace hoses, clamps, and filters as needed for proper sealing
• Adjust fuel pressure with the system regulator after installation
• Seek professional mechanical installation for tank-mounted pumps

Who is this for? EVIL ENERGY EFI 255LPH Intank Electric Fuel Pump Kit is aimed at automotive enthusiasts, tuners, and mechanics upgrading fuel delivery for higher-demand EFI setups or replacing an aging in-tank pump. It suits gasoline-powered 12V EFI vehicles that need increased flow for performance builds or steadier pressure under load, provided installers account for dimensional differences and follow recommended fuel-system practices.
