This info can all be found in the product details. Now let’s look closer at the different types of Mr Gasket regulators available.

Mr Gasket Carbureted Fuel Regulators

Carburetors need a steady fuel pressure between 3 and 7 psi. Fluctuations cause performance issues. Mr Gasket’s analog carb regulators are the gold standard.

They feature adjustable pressure control via an Allen set screw. This lets you dial in the optimal pressure for your carb. The screw tensions an internal spring connected to the diaphragm – increase tension for more pressure.

These regulators use high quality nitrophyl or neoprene rubber diaphragms. This gives exceptional durability and chemical resistance for long life.

They are available with 2 or 3 vacuum ports. Two ports are used on most universal applications. The third port gives you an extra vacuum source for accessories.

Mr Gasket carb regulators come in a range of inlet and outlet fitting sizes to accommodate various systems. Common sizes are -6AN, -8AN, and 1/2″ NPT inlet; 1/4″ or 5/16″ NPT outlet. Make sure to get the right fit.

If you want dead steady pressure, upgrade to their adjustable “Dial-A-Pressure” version. This uses a vernier secondary adjustment knob that reduces pressure creep. Ideal for finicky carbs.

For a billet aluminum housing, check out their new red anodized regulators. Very slick.

Mr Gasket Fuel Injection Regulators

Modern EFI systems need higher, more stable pressure – 40-120 psi depending on injector type. Mr Gasket’s electronic fuel injection regulators deliver rock solid control.

They feature adjustability via a 12V DC motor. This allows you to change pressure settings on the fly from your driver’s seat. It gives very precise control during tuning.

The electronic regulators use stainless steel internals and nitrophyl diaphragms for durability. Housings are black anodized aluminum for sleek looks and lightweight.

Injection regulators come with 2-port or 3-port options. The third port can be used for an external fuel pressure gauge to monitor setting changes.

High flow -6AN or -8AN inlet and outlet ports mean these regulators can meet the fuel demands of seriously modified engines. Make sure your system can keep up.

For import vehicles, Mr Gasket makes regulators specifically calibrated for Honda, Acura, Mitsubishi, Lexus, and others. This ensures correct pressure curves.

Shopping Tips for Mr Gasket Fuel Regulators

Here are some tips for getting the right fuel regulator at the best price:

• Shop online for the best selection of regulators. Local auto parts stores have limited inventory. Amazon is a top source.
• Join an online forum for your vehicle. Members often list discount codes for stores or manufacturers.
• Buy the regulator pre-tuned for your specific engine if available. Custom calibration saves hassles later.
• For older vehicles, a new reproduction regulator from Hawks Motors or Inline Tube can be an economical option.
• For a quick fix, rebuilding kits with gaskets, diaphragms, and hardware kits are way cheaper than new.
• During sales events like Black Friday or Cyber Monday, quality regulators deeply discounted. Stock up.

Now let’s dive into the installation process so your new regulator is up and running in no time.

How to Install a Mr Gasket Fuel Regulator

Replacing your stock fuel regulator is an advanced mechanic task. But the job is made much easier with Mr Gasket’s straightforward bolt-on design. Here are the steps:

1. Relieve Fuel Pressure – Disconnect the battery and release fuel system pressure before starting. This avoids dangerous fuel spraying.

2. Remove Old Regulator – Disconnect all fuel lines and vacuum hoses from the regulator being replaced. Remove mounting hardware and take it off.

3. Install New Regulator – Bolt the new Mr Gasket regulator in place of the old one. Use thread sealant on pipe connections if needed.

4. Hook Up Lines – Attach the feed and return lines to the matching inlet and outlet ports. Confirm a secure seat.

5. Connect Vacuum Lines – Based on your application, connect vacuum lines to the appropriate vacuum nipple(s) on the regulator.

6. Set Initial Pressure – Refer to your target fuel pressure and dial it in via the regulator’s adjustment screw or electronic control.

7. Reconnect Battery – With everything hooked up properly, reconnect battery power to test it out.

8. Troubleshoot – Start engine and use a fuel pressure gauge to set the final desired pressure. Fix any leaks found immediately.

Be sure to road test the vehicle and make tuning adjustments to the regulator as needed. Your engine will thank you for providing the optimal fuel supply.

Dialing in the Fuel Pressure for Maximum Performance

Adjusting fuel pressure is key to optimizing your vehicle’s air/fuel ratio. Your regulator’s adjustable design provides control over this critical variable.

Use these tuning tips to hone in the perfect fuel pressure:

• For carb engines, start in the 4-5 psi range and adjust up or down based on performance response.
• Watch your exhaust color. Dark tones mean rich fueling – lower pressure. Light tones equal lean – raise pressure.
• Install an oxygen sensor and gauge to read air/fuel ratios in real-time. Adjust the regulator to keep ratios within your target range.
• For boosted engines, run higher base pressure (~5 psi per 10 psi of boost) and use a regulator reference port for intake vacuum/boost.
• Log your pressure settings and find the one that gives max power based on G-tech acceleration runs or dyno testing.
• Road tune under hard acceleration, cruising, and light throttle. Your target fuel pressure may vary across driving conditions.

Patience and little tweaks go a long way. By optimizing your fuel supply, you’ll gain every last ounce of performance from modified engines.

Maintaining Your Mr Gasket Regulator for Longevity

Like any vital engine component, proper care of your Mr Gasket fuel regulator ensures it outlasts the rest of your upgrades. Follow this preventative maintenance plan:

• Use an inline fuel filter. This keeps particles from contaminating the regulator internals and causing wear.
• Install a fuel pressure gauge to monitor regulator health even if you don’t adjust pressure often.
• Replace the rubber diaphragms and gaskets about every 2 years or 30k miles. Kits are inexpensive insurance.
• Clean the regulator externally if it gets dirty. Mud or dust can impede heat dissipation and cause failure over time.
• Check all fittings and fix any leaks immediately. Weak seals decrease fuel pressure.
• Verify fuel compatibility if running ethanol blends or methanol. Upgraded Viton components may be needed.
• For occasional race use, rebuild the regulator more frequently. Hard use accelerates wear.
• If experiencing surging or odd performance, diagnose if the regulator could be at fault before replacing other parts.

Keeping your high performance investment in top shape gives you endless miles of boost-ready power.
