Vapor lock, a condition where the fuel somewhere in the system boils, causes fuel delivery to effectively stop. It can happen anywhere from the pump inlet all the way to the fuel rails or carburetor bowl. With pumps being about 1\/3 efficient, it is understandable that all of the OEM manufacturers are using a form of speed control to slow down the pump(s) during low fuel demand conditions.\u003c\/p\u003e\n\u003cp\u003eCombine high power pumps and engine heat that is returned to the fuel tank on a return type system, and the fuel tank becomes a large thermal battery. The hotter the fuel becomes, the more susceptible it becomes to vapor lock. It is common on warm days that the fuel tank becomes so hot that it becomes uncomfortable to keep a hand on it.\u003c\/p\u003e\n\u003cp\u003eLarge pumps like the TI Automotive\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e450\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eand\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e525lph\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003epumps can take\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e22+ amps\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eto drive at full power.

PWM is simply turning the pump on and off thousands of times per second. The longer the electrical pulse is on, the faster the pump spins. However, there must be some kind of input\/feedback to tell the electronics how to change the pump speed. Usually engine RPM, manifold absolute pressure (MAP), or throttle position sensor (TPS) feedback is used for return type fuel system speed control.\u003c\/p\u003e\n\u003cp\u003eImagine the engine in your car running at wide open throttle all the time.

Only a small fraction of the engine power is actually needed, hence, the need for a throttle. That is what PWM is for fuel pumps, a power throttling mechanism.\u003c\/p\u003e\n\u003cp\u003eThere are no switches, relays, or Hobb’s switches needed when using the ReturnX systems. The ReturnX controller has a primary and secondary output. The primary provides sufficient pump speed to maintain fuel pressure during idle\/cruise while the secondary pump follows at a lower duty cycle. This leader\/follower arrangement means no relays or Hobb’s switches, just a smooth ramp-up in pump speed until both pumps are at full output.\u003c\/p\u003e\n\u003cp\u003eFor carbureted and EFI applications, simply attach the supplied stand-alone MAP sensor hose to a manifold vacuum source (naturally aspirated) or past the supercharger\/turbocharger and make at-idle controller adjustments. The VaporWorx controller will do the rest.\u003c\/p\u003e\n\u003cp\u003eA return\/bypass type fuel pressure regulator is required.
