This regulator is engineered to work the same way Mazda designed the original system to work. With one regulator, with a return back to the tank. This ensures proper regulation of fuel pressure/pulse to the fuel injectors. Other products on the market piggy back a second regulator that does not return excess pressure to the tank but bleeds it off with the injectors opening and closing. This can cause an uneven pressure and pulse that the injectors can see, which can lead to fluctuating A/F ratios. In addition, regulating the fuel pressure by constricting the orifice size is tuning on the razors edge. You are limiting both the volume as well as the pressure of fuel supplied to the engine. This system does not limit the volume of the fuel, just the pressure it is delivered at. A large fluctuation of temperature when using "other products on the market" can lead to an extreme lean condition which can have catastrophic results, usually ending with an engine failure.

This kit is made to the highest standards using AN 6 and OE quick disconnect hardware. No hose clamps are used in this system at all. There is also no cutting or modifying of the OE hoses. All hoses are professionally made custom for the application and crimped to the fittings. The regulator is made by the leading manufacturer of fuel systems. This kit comprises all the best parts possible. Don't be fooled by cheaper inferior products on the market.

Our regulator is mounted in the trunk and not in the engine compartment. By mounting the kit in the trunk we keep it away from the heat of the engine compartment which can effect the temperature.

Adjustment is simple with one screw and the kit comes with a liquid filled gauge to monitor your pressure. There is also an additional un-used port on the regulator which can be used to add the optional fuel test port kit fitting.

Monitoring and tuning your AF ratio can help get the most performance out of your engine. This is the kit to have.

This kit comes complete with the following items:
  • Adjustable Fuel Pressure Regulator
  • Professionally made custom fuel lines (2)
  • Instructions
  • Liquid Filled Gauge
  • Replacement Fuel Line

Frequently Asked Shipping Related Questions:

Q: My order shipping transit time via Ground Shipping shows 3 Days. Why did I not receive my order in that time frame?
A: Ground shipping transit time is not a guaranteed delivery. This is based on items shipped from our current location with best time forecasted by the shipping company. Some items may ship from one our many warehouses across the US and can take longer to arrive to your shipping destination. Please use any of the faster methods to ensure your item arrives on time if you have any concerns about the delivery date.

Q: My order shipping method says UPS, but you sent me a FedEx tracking number. Am I getting someone else's order?
A: Here at Dfuser we use UPS Ground OR equivalent if you picked ground. Some orders may get shipped via Priority Mail if we determine that you will get your package sooner via that method. If you order something and want 1st, 2nd, or 3rd day shipping we reserve the right to use the carrier of our choice if we determine your package will get there in the same time period.

Q: My receipt says I was charged for 20lbs of shipping and the UPS tracking number only indicates that a 9lb package was shipped. Why did you charge me for a 20lb package?
A: Some items are larger than others and we need to enter DIMENSIONAL weight for shipping cost accuracy, especially for larger items that need to ship with express shipping. Carriers such as UPS & FedEx charge by dimensions, rather than weight.

Q: I received my item and upon opening it, the item is damaged! What do I do now?
A: First, please DO NOT install the product. Retain all packaging material, the damaged item, and anything else that came with the product. Call us right away so we can start a damaged shipment claim.
