Plobeda EFI Fuel Pressure Regulator Kit — Black 0–100 psi Gauge, AN6 Braided Lines

Plobeda's EFI fuel pressure regulator kit is an adjustable aluminum regulator and gauge assembly that controls fuel pressure from 0 to 100 psi for EFI systems and includes AN6 fittings and braided hose for a universal fit.

This compact kit pairs a lightweight anodized aluminum regulator with a 0–100 psi gauge, braided AN6 fuel lines and matching fittings to give tuners and DIY mechanics precise control over fuel pressure. It’s built for electric fuel-pump setups and designed to be a drop-in, adjustable solution for street cars, race builds and marine applications where steady fuel delivery is required. The kit balances accuracy, corrosion resistance and ease of installation so you can fine-tune fuel pressure without replacing the entire fuel system.

How do I adjust fuel pressure with this regulator?

Adjustment is straightforward: the regulator uses a hand-turning screw or knob to vary spring tension, and the included gauge shows the real-time pressure reading. Turn the adjuster slowly while the pump is running and monitor the gauge until the desired psi is reached; locking the adjuster secures the setting.

• Range: 0–100 psi for broad tuning flexibility
• Built-in gauge for live readings without extra tools
• Adjuster mechanism lets you fine-tune in small increments
• Threaded ports compatible with AN6 fittings in the kit

Will this fit my EFI-equipped car or boat?

The kit is engineered as a universal solution for most EFI systems that use AN6 plumbing or can adapt to AN6. It works best with electric in-tank or in-line pumps that deliver a steady flow and is suitable for many automotive and marine engines when AN6 plumbing is appropriate.

• Universal AN6 fittings reduce the need for custom adapters
• Compatible with common electric fuel pump setups
• Aluminum construction resists corrosion in wet environments
• Does not require special programming or ECU changes

What components come in the kit and how durable are they?

The package includes a machined aluminum regulator, an adjustable 0–100 psi pressure gauge, seven AN6 fittings and three stainless-steel braided 6AN fuel hoses. Materials are chosen for strength and light weight; aluminum alloy and braided lines give a balance of corrosion resistance and long service life when installed correctly.

• 1× aluminum adjustable fuel pressure regulator (anodized finish)
• 1× 0–100 psi pressure gauge for immediate feedback
• 7× AN6 fittings for inlet/outlet and return plumbing versatility
• 3× stainless-steel braided AN6 fuel hoses for flexible connections

How should I install the Plobeda regulator safely?

Install the regulator in the return or bypass line according to your vehicle’s plumbing layout, secure all AN6 fittings with the correct torque and route fuel lines away from heat sources and moving parts. Always depressurize the fuel system first, test for leaks with the pump powered but engine off, and recheck fittings after initial operation.

• Depressurize system before disconnecting fuel lines
• Use thread sealant where recommended for AN fittings
• Position gauge for clear visibility during tuning
• Inspect for leaks after first run and after a few heat cycles

Who is this for: Enthusiasts, tuners and mechanics who need a reliable, adjustable fuel pressure solution for electric-pump EFI systems will find this Plobeda kit practical and cost-effective. It’s ideal for performance street builds, track cars, custom projects and marine engines that accept AN6 plumbing and require on-the-fly pressure control. If you want a compact aluminum regulator with a wide 0–100 psi range, an integrated gauge and a full complement of AN6 fittings and braided hoses, this kit provides a ready-to-install option to help you dial in fuel delivery.
