Overview

Meet the FQRANBO 12-804 adjustable fuel pressure regulator, a direct-fit solution for Holley and Edelbrock carburetors. Engineered to deliver precise fuel pressure in the practical 1 to 4 psi range, it supports a 0.220 inch restrictor orifice to help shape flow characteristics while you tune for your setup.

What makes it stand out

  • COMPATIBILITY AND RANGE: Direct fit for Holley and Edelbrock carbs; adjustable 1 to 4 psi keeps fueling predictable across RPM.
  • PORTS AND GAUGE: 3/8 inch NPT gauge port with a liquid-filled gauge for smooth, readable pressure readings during tuning.
  • CONTROL AND STABILITY: An internal pressure-stabilizing structure and a user-friendly adjustment knob let you dial in the desired pressure with confidence.
  • BUILD AND DURABILITY: Durable metal and ABS construction withstands high temperatures and corrosive environments in rugged engine bays.
  • INSTALLATION NOTES: Loosen the hex nut, adjust to the target pressure, then re-tighten to avoid leaks or lockouts.
  • PRECISION SCALE: Upgraded minimum scale of 1 psi reduces misreadings and helps you track real pressure changes more reliably.

Real world usage

  • Engine swaps or carburetor upgrades where stable fuel delivery matters during idle and accelerations.
  • On-dyno tuning sessions to observe how pressure responds to load and RPM changes.
  • Any setup that benefits from a clear gauge readout and flexible pressure control without adding complexity.

What you get and how it helps

This regulator sits between the fuel pump and carburetor, regulating pressure with a precision knob and an internal stabilizing structure. A 0.220 inch restrictor helps modulate flow for smoother metering, while the 1 in / 2 out configuration supports common carburetor plumbing layouts. The solid metal and ABS mix is built to endure demanding engine environments, so you can tune with confidence and focus on the drive, not the regulator.

Tips for best results

  • Confirm compatibility with your carburetor model before installation for a seamless fit.
  • During setup, adjust in small increments and verify readings with the gauge at operating temperature.

FAQ

Q: Is the FQRANBO 12-804 regulator compatible with Holley and Edelbrock carburetors?

A: Yes, it directly fits Holley and Edelbrock carbs and lets you tune fuel pressure from 1 to 4 psi.

Q: How do I adjust the fuel pressure on this regulator?

A: Loosen the hex nut, rotate the adjustment knob to your desired pressure, then re-tighten the nut.
