YESHMA Fuel Pressure Regulator Kit — Adjustable 0–100 psi Gauge, 6AN Fittings (Black)

YESHMA EFI Fuel Pressure Regulator Kit is an adjustable aluminum regulator with an integrated gauge and 6AN fittings that lets you set and monitor fuel pressure for most EFI systems between 30–70 psi.

This complete kit gives tuners and DIY mechanics a durable, serviceable way to control fuel pressure at the rail. Built from anodized aluminum with stainless-steel and CPE hose sections, the regulator includes a visible gauge and multiple 6AN adapters to fit a wide range of setups. The package is designed for universal EFI compatibility and includes bracketry and fittings for a straightforward install when performed by a qualified technician.

How does the regulator let me control fuel pressure?

The regulator’s threaded adjustment and visible gauge let you dial in rail pressure precisely. Turn the adjuster while observing the gauge needle to raise or lower pressure within the working range, then secure the lock to hold the setting.

• Adjustable range designed to operate reliably between 30 and 70 psi.
• Clear 0–100 psi gauge for quick visual verification.
• Locking mechanism keeps the setting steady under vibration.

What parts are included and what materials are used?

The kit comes with all the core components needed to plumb a fuel rail feed and return in most EFI systems. Components are selected for corrosion resistance and workshop durability.

• One anodized aluminum regulator and one 0–100 psi dial gauge.
• Three straight 6AN adapters, three 90° 6AN adapters and one 6AN port plug.
• Fuel rail adapter, regulator mounting bracket and three sections of 6AN-rated fuel line made from 304 stainless braid over CPE synthetic rubber.

Will this fit my vehicle and how universal is it?

The YESHMA regulator kit is designed as a universal EFI accessory for most aftermarket and factory-style fuel rails. Fitment depends on available 6AN connections or adapter compatibility on your vehicle’s fuel system.

• Works with common EFI setups that accept 6AN fittings or can be adapted with included hardware.
• Universal rail adapter helps match many fuel rails without custom fabrication.
• Professional installation is recommended to ensure correct plumbing and safety.

How should I handle installation and safety concerns?

Fuel system work carries safety risks; follow workshop best practices and local regulations. Use proper clamps, check for leaks at operating pressure, and replace fuel filters as part of the install process.

• Bleed and pressure-test the system after installation to confirm leak-free operation.
• Keep fittings torqued to specification and replace any damaged hose or seals.
• Instruction sheet is not included; consult a trained technician or OEM service guide.

Who is this for: The YESHMA EFI Fuel Pressure Regulator Kit is aimed at performance enthusiasts, tuners, and professional mechanics who need a reliable, adjustable pressure control for aftermarket or modified EFI systems. If you want precise pressure control, visible monitoring, and a package of multiple 6AN fittings for flexible plumbing, this kit provides the core hardware—just plan for professional installation or experienced DIY work.
