TEMSONE Adjustable Carb Fuel Pressure Regulator Kit 1–5 psi — Universal with 8mm & 10mm Adapters, Includes Hoses

TEMSONE Adjustable Carb Fuel Pressure Regulator Kit is a universal, manual deadhead-style regulator that lets you set fuel pressure from 1 to 5 psi for carbureted engines using included 8mm and 10mm adapters.

This compact fuel pressure regulator controls upstream pressure by restricting flow between the fuel pump and carburetor. Designed for carbureted engines, the unit is adjustable, straightforward to install, and compatible with most stock and aftermarket pumps that deliver up to 7 psi input pressure. The kit ships with hoses, rubber tails and clips so you can complete a basic installation quickly.

How does this regulator change fuel delivery for a carburetor?

The TEMSONE regulator is a deadhead-style device that lowers fuel pressure by restricting flow, allowing finer control over the pressure delivered to the carburetor. Turning the adjustment knob or screw increases or decreases the restriction, which in turn sets the downstream pressure within the 1–5 psi range.

• Adjustable range: 1–5 psi for carburetor tuning.
• Max input pressure: 7 psi, suitable for most low-pressure fuel pumps.
• Max flow capacity: 150 liters per hour to support a variety of engines.
• Deadhead design provides stable, repeatable pressure control.

What comes in the package and is installation difficult?

The kit includes one fuel pump regulator, four connection pipes, four rubber tails, and three clips so you have hoses and fittings for a standard install. Installation is typically done between the fuel pump and the carburetor on the fuel line and requires basic hand tools; no special calibration equipment is necessary.

• Complete kit: regulator, hoses, rubber tails, and clips included.
• Installation location: inline between pump and carburetor.
• Tools required: common hand tools and simple hose clamps.
• Quick setup: basic mechanical skill recommended, instructions implied.

Will this regulator fit my engine and fuel pump?

TEMSONE designed this regulator for wide compatibility with most carbureted engines, using 8mm and 10mm adapter fittings for common fuel lines. It’s best suited for systems where the fuel pump produces up to 7 psi and the engine’s fuel demand does not exceed the 150 lph flow rating.

• Universal fitment for most carbureted setups.
• Includes 8mm and 10mm adapters for common fuel line sizes.
• Check pump output: intended for pumps with ≤7 psi output.
• Flow limit: 150 lph—verify against your engine’s needs.

How should I use the adjustment and maintain the unit?

Make incremental adjustments while monitoring fuel pressure or engine performance. Periodically inspect hoses, clamps and rubber tails for wear, and ensure the regulator isn’t exposed to excessive heat or corrosive fluids to prolong service life.

• Adjust in small steps while observing engine idle and fuel delivery.
• Inspect fittings and hoses routinely for leaks or degradation.
• Avoid mounting near extreme heat sources or exhaust components.
• Service support: TEMSONE offers 1 year of product quality support.

Who is this for: The TEMSONE Adjustable Carb Fuel Pressure Regulator Kit suits DIY mechanics, vintage car restorers, small engine tuners and anyone running a carbureted engine who needs precise low-pressure fuel control. If you use a low-pressure pump (≤7 psi) and want a simple, adjustable regulator with basic installation accessories, this kit delivers practical, universal compatibility and one-year support for peace of mind.
