The Aeromotive 66162 ReturnX Fuel System Controller offers numerous advantages for high-performance automotive applications, including precise fuel pressure regulation, return-type design, adjustable fuel pressure, durable construction, and an integrated fuel pressure gauge. However, its higher cost and complex installation may be disadvantages for some users. Ultimately, the decision to purchase the Aeromotive 66162 ReturnX depends on the specific requirements and budget of the user.

If you are looking for a high-performance fuel pressure regulator for your automotive application and have the budget for it, the Aeromotive 66162 ReturnX Fuel System Controller is an excellent choice. Its precise fuel pressure regulation, return-type design, adjustability, durability, and integrated fuel pressure gauge make it a popular and reliable option for high-performance applications. However, if you are working with a limited budget or do not require the advanced features of the Aeromotive 66162 ReturnX, there are other, more affordable fuel pressure regulators on the market that may better suit your needs.

Details:

Over-temperature shutdown with automatic reset that will operate indefinitely without damage. Only a small fraction of the engine power is actually needed, hence, need for throttle. Various return type pressure regulators can be used with the ReturnX systems. That is what PWM for fuel pumps, a power throttling mechanism.

The hotter the fuel becomes, more susceptible it becomes to vapor lock. Single and dual pump control systems for naturally aspirated supercharged applications. The primary provides sufficient pump speed to maintain fuel pressure during idle/cruise while the secondary follows at a lower duty cycle. Aeromotive has a variety of regulators that will work well LINK TO AEROMOTIVE REGULATORS.

The Naturally Aspirated or Supercharged controller version should be chosen based on the engine configuration. A return/bypass type fuel pressure regulator is required. This leader/follower arrangement means no relays or Hobbs switches, just a smooth ramp-up in pump speed until both pumps are at full output. Vapor lock, a condition where the fuel somewhere in system boils, causes delivery to effectively stop.

A significant reduction in the average fuel pump power requirement resulting lower temperatures and longer life. Imagine the engine in your car running at wide open throttle all time. High-horsepower pumping systems can create excessive heat that lead to vapor lock.

Key Features: Works with all brushed type fuel pumps. The ReturnX Controller includes these standard features: Everything needed electrically to drive the fuel pump. Aeromotive has a variety of regulators, filters, and fuel lines to meet any need. Integrates into the OE ECM to allow all safety systems remain functional.

Stand-alone MAP-based fuel pump speed control. For carburetors and EFI applications, simply attach the supplied stand-alone MAP sensor hose to a manifold vacuum source naturally aspirated or past supercharger/turbocharger make at-idle controller adjustments. Following are some guidelines: Adjustable deadhead or full return regulators: Standard return/bypass type regulators can be used in either constant/static manifold referenced fuel pressure modes. Typical power reduction to the pump of 45-75%.

No relays or Hobbs switches needed. The longer the electrical pulse is on, faster pump spins. PWM is simply turning the pump on and off thousands of times per second. Positive and negative turn-on triggers included.

OEM Delphi/Apt iv connections for terminals, seals, and connector bodies. There are no switches, relays, or Hobbs switches needed when using the ReturnX systems. If the controller is MI's-matched to induction type an incorrect pump speed ramp rate will occur and possibly lead a lean condition. It can happen anywhere from the pump inlet all way to fuel rails or carburetor bowl.

All cross-linked polyethylene wiring. The lower the fuel pressure, easier pump and injectors must work. Can be used with voltage boosters. The lower, the better, as long fuel injector has sufficient capacity.

With pumps being about 1/3 efficient, it is understandable that all of the OEM manufacturers are using a form speed control to slow down pump during low fuel demand conditions. Since the vacuum is so low there little range for MAP sensor to operate. Large pumps like the TI Automotive 450 and 525lph can take 22 amps to drive at full power. The ReturnX controller has a primary and secondary output.

The Paperwork's controller will do the rest. Carburetor and EFI capability. Short circuit output protection that will operate indefinitely without damage.
