Fuelab Tech Tips: Return Line Plumbing

The purpose of this video is to demonstrate the effect of having an overhead splash return instead of having the return below the surface, such as using a dip tube.

Interesting Facts: The voltage output reading, next to the pressure gauge in the video, indicates the reading directly from the 529xx Series Electronic Regulator. Each 529xx Series Regulator has an analog output that can be monitored through either a voltmeter for diagnostics or a data logger system for fuel system performance tracking. As shown in video, the idle condition (no additional engine load) shows the system at about a 1.5 Volt output. At fuel throttle or full demand the output gets up to about 5.0 Volts.

The fuel pump used in this video is a Fuelab Model 42402-2, the regulators used in this video are a Fuelab Model 52902-1 (Electronic) and a Fuelab Model 52501-1 (In-Line).
