1 - 4 PSI Aluminum Fuel Pressure Regulator - Black

• Adjustable 1–4 PSI regulator holds stable pressure for carbureted fuel systems

• Non-return, inline design installs directly in your fuel supply line

• Mounting bracket included; fittings, gauge, and gauge port not included

• 3/8" NPT threaded inlet/outlet, chrome aluminum body, not rebuildable

This adjustable fuel pressure regulator is built for carbureted fuel systems, with a 1–4 PSI range for dialing in stable, consistent fuel delivery. It uses a non-return design and mounts inline in your fuel supply line, with a mounting bracket included for straightforward installation.

The regulator body is aluminum with a black finish, using 3/8" NPT threaded inlet and outlet ports. Fittings, a fuel pressure gauge, and a gauge port are not included and must be sourced separately if needed. This unit is not rebuildable — confirm your fuel delivery type, pump capacity, and pressure requirements before final installation.

Applications
Fits any gasoline, carbureted fuel system requiring 1–4 PSI regulation — commonly used in street performance builds, restorations, and custom fuel system setups. This is a carbureted-specific regulator; it is not designed for EFI/fuel injection systems, which typically require higher pressure ranges.

Installation
Mounts inline using the included bracket. Confirm port sizing (3/8" NPT), hose routing, and return-line requirements before installation, since fittings are not included. Verify your fuel pump's output capacity is compatible with this regulator's 1–4 PSI range before final setup.

What pressure range does this regulator support?
This fuel pressure regulator is adjustable from 1 to 4 PSI, making it ideal for carbureted fuel systems that require low fuel pressure.

Is this compatible with EFI/fuel injection systems?
No. This regulator is designed exclusively for carbureted fuel systems. Electronic fuel injection (EFI) systems require significantly higher fuel pressure and are not compatible with this regulator.

Does this include a fuel pressure gauge or gauge port?
No. This regulator does not include a fuel pressure gauge or a dedicated gauge port.

Does this include fittings?
No. Fuel line fittings are not included and must be selected separately based on your fuel line size and installation requirements.

Is this regulator rebuildable?
No. This fuel pressure regulator is not designed to be rebuilt.

What port size does this regulator use?
The regulator features 3/8-inch NPT threaded inlet and outlet ports.

Does this include a mounting bracket?
Yes. A mounting bracket is included for convenient inline installation.

Is this a return-style or non-return regulator?
This is a non-return (dead-head) fuel pressure regulator designed for inline installation in the fuel supply line between the fuel pump and carburetor.
