Key Features & Advantages🔹 Precision Pressure Control for Carburetors

• Fine-tune pressure to match carb specs: 2–3 PSI (single-barrel carbs) / 4–5 PSI (high-performance twin carbs)
• Eliminates rough idling, acceleration hesitation, and power loss caused by improper fuel pressure
• Critical Limitation: Not suitable for fuel injection (requires 30–60 PSI, far beyond this regulator’s capacity)

🔹 150 LPH High Flow for Performance Engines

• Handles fuel demand for street driving, drag racing, and off-road use (supports up to 400 HP)
• 7 PSI max input pressure compatible with most mechanical/electric carburetor fuel pumps
• Prevents over-pressurization that damages carb floats or causes fuel leaks

🔹 Durable All-Metal Build

• Aluminum alloy body resists underhood heat (up to 250°F/121°C), fuel corrosion, and vibration
• No warping or cracking (unlike plastic regulators) for long-term reliability

🔹 Complete DIY Installation Kit

• All parts included for 30–45 minute install: rubber tails, 8mm/10mm connection pipes, fastening clips
• No extra adapters needed – fits most standard carburetor fuel lines
• Universal mounting (bracket not included; use existing hardware or generic 56.5mm mount)

3. Compatible Engines & VehiclesWorks with carbureted engines only, regardless of make/model:

• Classic cars: Ford Model A, Chevy 350, Mopar 318
• Hot rods/custom builds: Small-block V8s with Holley, Edelbrock, Weber carbs
• Vintage motorcycles: Harley-Davidson Shovelhead, Yamaha XS650 (carb models)
• Off-road vehicles: Jeep CJ-7 (pre-1991), carbureted ATVs

Fuel Compatibility: Gasoline (leaded/unleaded), E10/E15 ethanol blends | NOT for diesel/methanol4. Step-by-Step Installation Tips

1. Safety First: Disconnect battery and relieve fuel pressure (run engine until it stalls).
2. Mount Regulator: Install between fuel pump and carburetor (as close to carb as possible) on a cool, non-vibrating engine bay spot.
3. Connect Lines: Attach included 8mm/10mm pipes to regulator ports; use rubber tails and clips to link to existing fuel lines (tighten to prevent leaks).
4. Adjust Pressure: Set dial to carb manufacturer’s specs (2–3 PSI single carb / 4–5 PSI twin carb). Pro Tip: Use a fuel pressure gauge (not included) for precise calibration.
5. Test for Leaks: Turn key to “on” (don’t start) and check all connections. Adjust clips if leaks occur.
6. Fine-Tune: Start engine, warm up, and adjust pressure further if hesitation or rough idling occurs.

Important Notes

• Carburetor Only: Never use with fuel injection, direct injection, or turbocharged engines requiring high pressure (risk of severe engine damage).
• Shipping: Dispatched within 24 hours (excluding weekends/holidays) from CA/NJ warehouses.
• Issue Resolution: Contact seller first (before response) if regulator leaks, doesn’t fit, or fails to adjust pressure. Provide photos of the issue and engine type for prompt solutions (replacement/refund/install help).
• Tolerance: Manual measurement may cause 1–3mm size differences – no impact on fitment/performance.
