EVIL ENERGY 6AN Male to Female Fuel Pressure Take-Off Fitting – 1/8″ NPT Gauge Port
Upgrade your fuel system with the EVIL ENERGY 6AN Male to Female Fuel Pressure Take-Off Fitting, a compact aluminum adapter designed to add a fuel pressure gauge, electronic pressure sensor, or monitoring device to a custom -6AN fuel line.
Manufactured from durable 6061-T6 aluminum alloy, this inline fuel pressure adapter features a 6AN male inlet, 6AN female outlet, and 1/8-inch NPT auxiliary port, allowing enthusiasts and professional engine builders to monitor fuel pressure without replacing an entire fuel line assembly.
Whether you’re installing an aftermarket fuel pressure regulator, upgrading to E85, building a turbocharged fuel system, or plumbing an LS engine swap, this EVIL ENERGY fuel pressure take-off fitting provides a convenient solution for adding fuel pressure monitoring to compatible AN fuel plumbing.
Why Choose the EVIL ENERGY 6AN Fuel Pressure Take-Off Adapter?
Accurate fuel pressure monitoring is essential for diagnosing fuel delivery problems and maintaining consistent engine performance.
Insufficient fuel pressure can contribute to lean operating conditions, hesitation, poor acceleration, and potentially serious engine damage under heavy load.
The EVIL ENERGY 6AN fuel pressure take-off fitting allows you to install a compatible pressure sensor or gauge directly into an existing -6AN fuel line connection.
Key Features and Benefits
-
6AN male-to-female configuration: Designed for installation between compatible -6AN fuel line components.

1/8″ NPT gauge port: Accommodates compatible mechanical pressure gauges, electronic sensors, and pressure transducers.
-
6061-T6 aluminum construction: Lightweight, corrosion-resistant material suitable for performance fuel plumbing.
-
37-degree AN flare sealing: Provides a mechanical sealing surface without requiring thread sealant on the AN connection.
-
1,500 PSI maximum advertised working pressure: Suitable for applications within the manufacturer’s specified pressure limits.
-
-40°F to 250°F operating temperature: Designed for a broad range of automotive operating conditions.
-
Compact inline design: Simplifies pressure monitoring without requiring a separate gauge-port fuel rail or regulator.
Add a Fuel Pressure Gauge or Sensor to Your 6AN Fuel Line
Installing a fuel pressure gauge is one of the most useful upgrades for a custom fuel delivery system.
The EVIL ENERGY fuel pressure take-off adapter makes it possible to monitor fuel pressure at a suitable point in the fuel line using the integrated 1/8″ NPT port.
Depending on the application, the port can accommodate:
-
Mechanical fuel pressure gauges with compatible 1/8″ NPT connections
-
Electronic fuel pressure sensors
-
Aftermarket ECU fuel pressure transducers
-
Fuel pressure diagnostic equipment
-
Data logging sensors for performance tuning
For engine management systems that support fuel pressure compensation or safety strategies, a properly installed sensor can provide valuable information about fuel delivery under load.
Important: The adapter provides a pressure measurement connection only. It does not regulate fuel pressure, increase fuel flow, or include a pressure sensor.

Ideal for E85 Conversions and Performance Fuel Systems
Converting a performance vehicle to E85 often requires upgrades to fuel pumps, injectors, fuel lines, and engine management calibration.
Monitoring fuel pressure becomes especially important because E85 typically requires substantially more fuel volume than gasoline to support comparable engine output.
This EVIL ENERGY 6AN take-off fitting can be incorporated into compatible aftermarket fuel systems to provide a dedicated pressure monitoring port.

When using ethanol-blended fuels, verify the compatibility of the complete assembly, including the fitting, pressure sensor, seals, and any thread sealant.
Precision 37-Degree AN Flare Connections
The EVIL ENERGY adapter features industry-standard -6AN connection geometry.
The male and female AN connections use 37-degree flare sealing surfaces designed to create a secure metal-to-metal seal when properly assembled.
The -6AN connection uses 9/16-18 UNF threads.
Unlike tapered pipe fittings, AN flare connections seal at the flare surface rather than through the threads.
Do not apply PTFE tape or thread sealant to the AN flare connections.
1/8″ NPT Pressure Gauge Port
The auxiliary port uses 1/8″ NPT tapered pipe threads. Choosing the right performance fuel pump is crucial to any build, learn all about it using our DIY guide.
NPT connections rely on tapered thread engagement and an appropriate compatible thread sealant to create a leak-resistant connection.
Use a fuel-compatible liquid thread sealant approved for the application. Avoid excessive sealant, which can enter the fuel system or obstruct a pressure sensor.

Vehicle compatibility depends on the installed fuel system and available -6AN connections. Factory fuel rails and OEM quick-connect fuel lines may require additional adapters.
How to Install a 6AN Fuel Pressure Take-Off Fitting
-
Relieve fuel system pressure according to the vehicle manufacturer’s service procedure.
-
Disconnect the battery and work in a well-ventilated area away from ignition sources.
-
Identify an appropriate -6AN connection where fuel pressure should be measured.
-
Install the adapter between compatible male and female AN connections, verifying correct flare engagement.
-
Install the fuel pressure gauge or sensor into the 1/8″ NPT port using suitable fuel-compatible thread sealant.
-
Tighten fittings according to the component manufacturers’ specifications without overtightening.
-
Prime the fuel system and inspect all connections for leaks before starting the engine.
-
Verify fuel pressure readings against the vehicle’s expected operating specifications.

Why Fuel Pressure Monitoring Matters
A fuel pressure gauge or sensor can help identify problems such as inadequate fuel pump delivery, restricted filters, faulty regulators, and pressure loss under high engine demand.
For turbocharged and supercharged engines, monitoring fuel pressure under boost can be particularly valuable.
This EVIL ENERGY fitting offers a straightforward way to add that monitoring capability to a compatible -6AN fuel system. Want to convert to E85? Check out our E85 conversion guide here.
