• Operating temperature range: -68°F to 194°F
• Sealed design and materials selected for varied fuel types

What comes in the box and how easy is installation?

EVIL ENERGY supplies a complete mounting and connection kit so you can install the pump below the fuel tank for gravity-fed inlet flow. The package includes a bracket, gaskets, adapters, terminals, and a user manual that walks through fitting and wiring, reducing guesswork during installation.

• Included: pump, 60mm mounting bracket, 2 gaskets, washer, 2 nuts
• Electrical and hose accessories: 2 insulated terminals, 10AN inlet adapter, 6AN outlet adapter
• Extras: 2 rubber connection covers and a detailed user manual

How should I position and wire the pump for best performance?

For reliable priming and longevity, position the pump below the fuel tank so fuel can gravity-feed into the inlet. Use the supplied bracket and hardware for secure mounting, and follow the manual for correct 12V wiring and fuse placement to protect the circuit.

• Mount beneath the tank to maintain gravity-fed inlet flow
• Secure with the included 60mm bracket and fasteners
• Wire to a 12V DC supply with appropriate fuse and use insulated terminals

Who is this for: The EVIL ENERGY 300LPH inline pump suits performance car builders, tuners, and diesel or EFI conversion projects that need a robust, high-flow external pump with comprehensive mounting hardware. Choose this unit when you require a dependable 12V pump with broad fuel compatibility, strong tested flow rates, and a kit that simplifies installation.
