About this item
EVIL ENERGY delivers a complete carbureted fuel delivery solution: a high-flow 12V electric fuel pump (external mount, up to 370 LPH), an adjustable 4.5-9 PSI fuel pressure regulator with gauge, and 20 FT of 6AN fuel line - choose the PTFE braided line (E85 / alcohol) or the NBR rubber line (gasoline / diesel). One box, matched fittings, no second order.
Key Features
-
COMPLETE CARBURETED KIT: 12V pump + 4.5-9 PSI regulator + 20FT fuel line, all fittings matched so there is no barb-versus-AN mismatch.
-
4.5-9 PSI WITH GAUGE: dial pressure to the carburetor's spec and verify on the included 5-12 PSI gauge - stops flooding at idle and lean-out at wide-open throttle.
-
EXTERNAL GEAR PUMP: 12V-13.5V, 345-370 LPH, aluminum body, -68°F to 194°F - no in-tank install, DIY friendly.
-
TWO FUEL LINES: NBR rubber (650 PSI working) for gasoline / diesel, or PTFE braided (1500 PSI working, E85-rated hose) for alcohol blends and high-heat bays. The included pump runs gasoline / diesel only.
-
CARBURETOR ONLY: built for low-pressure carbureted systems - classic muscle cars, hot rods, motorcycles, generators and small engines.
Evil Energy Carburetor Systems: All-in-One Carbureted Engine Solution
Tailored exclusively for carbureted engines, the bundle integrates a high-performance external fuel pump and a precise pressure regulator. It eliminates separate part sourcing while ensuring seamless component compatibility - ideal for classic car restorations, hot rod builds, and small carbureted engine maintenance.
This EVIL ENERGY kit completes the package with professional-grade 6AN fuel line (PTFE or NBR), creating a true one-stop solution from tank to carburetor.

High-Performance 12V Electric Fuel Pump for Carburetor
-
Gear-type external design: no in-tank installation required, simplifying setup for DIY enthusiasts and professional modifiers.
-
12V-13.5V DC compatibility: matches standard automotive electrical systems to avoid power mismatches.
-
Weather-resistant aluminum body: -68°F to 194°F range for reliable operation in cold, heat or engine-bay conditions.
-
Gasoline & diesel only: use with an inline filter for optimal pump longevity (not rated for E85 / alcohol).

Adjustable 4.5-9 PSI Fuel Pressure Regulator for Carburetor
-
4.5-9 PSI adjustable range: suits carburetor pressure demands, preventing flooding from excessive pressure and fuel starvation from low pressure.
-
Multi-fuel regulator: works with gasoline, diesel, E85 and ethanol / alcohol (note: the NBR hose variant is not for E85 - choose the PTFE variant).
-
Built-in gauge & durable build: includes a 5-12 PSI gauge for real-time checks; 6061-T6 aluminum alloy body for long-term use.
-
Two outlet styles: NBR variant ships 3/8 NPT to 3/8 Barb fittings ; PTFE variant ships 3/8 NPT to 6AN fittings

NBR Rubber vs PTFE Braided Fuel Line: Which Variant?
-
Choose the NBR rubber variant: for gasoline and diesel street builds: 3/8 in push-lock hose, 650 PSI working, 10 hose clamps, lowest cost and easy routing. Not for E85.
-
Choose the PTFE variant : for E85, alcohol blends or high-heat / high-pressure systems: 6AN PTFE braided hose, 1500 PSI working, full set of 0°/45°/90°/180° AN hose ends.
Seamless Component Compatibility
-
Matching connections: the 12V pump (3/8 in ports) and the 4.5-9 PSI regulator (3/8 NPT ports) link through the 20FT fuel line and its fittings - NBR variant uses push-lock barb joints, PTFE variant uses 6AN flare joints, both leak-minimized.
-
Complete hardware: pump adapters, regulator fittings, gauge, bracket, port plug, clamps or AN ends and screws are all in the box for immediate assembly. See the carburetor fuel pressure regulator, PTFE fuel line kit and NBR fuel hose kit for individual specs.

Versatile Application Across Equipment
Optimized for 1960s-1980s muscle cars, hot rods, motorcycles and generators - covering common carbureted vehicle and equipment types for reliable daily and hobbyist performance.
