Adjustable Fuel Pressure Regulator - Black

• Adjustable 1–6 PSI regulator holds stable pressure for carbureted fuel systems

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

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

• 0.375 in. NPT threaded inlet/outlet, chrome aluminum body, not rebuildable

This adjustable fuel pressure regulator is built for carbureted fuel systems, with a 1–6 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 and fittings included for straightforward installation.

The regulator body is aluminum with a chrome finish, using 0.375 in. NPT threaded inlet and outlet ports. A fuel pressure gauge and gauge port are not included. 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 1–6 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.

Installation
Mounts inline using the included bracket and fittings. Confirm port sizing (0.375 in. NPT), hose routing, and return-line requirements before installation.

What pressure range does this regulator support?
This fuel pressure regulator features an adjustable pressure range of 1 to 6 PSI and is designed for carbureted fuel systems.

Is this compatible with EFI or fuel injection systems?
No. This regulator is designed exclusively for carbureted fuel systems. Electronic fuel injection (EFI) systems require significantly higher fuel pressure and a different style of regulator.

How is this different from TSP's other carbureted regulators?
TSP offers carbureted fuel pressure regulators with adjustable pressure ranges of 1–4 PSI, 1–6 PSI, 4.5–9 PSI, and 5–12 PSI. This 1–6 PSI model provides a versatile adjustment range suitable for many carbureted fuel system applications.

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 and a mounting bracket?
Yes. The regulator includes the required fittings and a mounting bracket for installation.

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

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

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.
