Pilida Fuel Pressure Regulator Kit 1–5 PSI Manual Adjustable — Zinc-Alloy Body, Numbered Dial

This compact regulator gives you precise fuel pressure control for carbureted engines, featuring a numbered top dial, corrosion-resistant zinc-alloy body, and three common fuel fittings. It is built for durability with an anodic oxidation finish and ships with 1/4", 5/16", and 3/8" fuel adapters so you can match most existing fuel lines. Follow installation notes—use thread seal tape on fittings and do not exceed the 7 PSI maximum input pressure—to ensure leak-free, reliable operation.

How does this regulator improve carburetor performance?

Keeping fuel pressure steady at the carburetor helps the float and jets meter fuel more consistently, reducing flooding or lean running caused by pressure fluctuations. The Pilida 9710 offers a clear, numbered adjustment so you can fine-tune pressure between 1 and 5 PSI to suit specific engine setups.

• Adjustable 1–5 PSI range for precise tuning
• Numbered dial for repeatable settings
• Helps stabilize float bowl fuel level under varying pump output

What are the build quality and durability features?

The regulator body is made from zinc alloy and finished with an anodic oxidation process to resist corrosion and wear in engine bay environments. Its compact, machined construction reduces the risk of leaks or mechanical failure when installed correctly.

• Zinc-alloy housing for strength and longevity
• Anodic oxidation finish for enhanced corrosion resistance
• Robust fittings designed for repeated assembly and service

Which fittings and installation tips should I know about?

The kit includes three fuel adapters—1/4", 5/16", and 3/8"—to fit common fuel line sizes without extra parts. Use thread seal tape on the threaded connections to prevent leaks, and never subject the regulator to more than 7 PSI input pressure.

• Includes 1/4", 5/16", and 3/8" fuel adapters for broad compatibility
• Use thread seal tape on fittings for leak prevention
• Maximum allowed input pressure: 7 PSI—do not exceed

How do I set and adjust the pressure for my engine?

Start with the dial at a low pressure setting and gradually increase while observing engine response or using a fuel pressure gauge at the carburetor. Make small increments, note the numbered dial position for repeatability, and confirm stable idling and throttle response before finalizing the setting.

• Begin at a low dial setting and increase incrementally
• Use a fuel pressure gauge at the carb for verification if available
• Record dial position for future reference or reinstallation

Who is this for: The Pilida 9710 regulator kit is aimed at DIY mechanics, small-engine specialists, and anyone running carbureted vehicles or equipment with Facet-style pumps who need precise fuel pressure control. It’s appropriate for cars, trucks, boats, generators, and other carbureted engines where a compact, adjustable regulator and multiple adapter sizes are required. If you rely on consistent carburetor fuel delivery and want corrosion-resistant hardware with a clear adjustment method, this kit is made to fit those needs.
