Procedure and documentation of building a high performance fuel system for a boosted L.S. engine. In this particular case we are installing a high performance return style fuel system using a Magnafuel MP-4303  Pro-tuner 750 fuel pump, on our turbo charged 6.0 L.S. in a  1980 Ford Thunderbird ( fox body ). Also installing the Auto meter fuel bridge for a working after market fuel gauge to work with our non-standard Ford gas tank sending unit ( 85 ohm's empty & 10 ohm's full ) . We also turn the Pro-tuner 4303 Magnafuel pump on with fuel running through it, for those interested to see how loud the pump is.  Fuel system is installed before we can install our Holley Terminator X-max ecm in Project Turbo L.S. Update----- The stock fuel pressure regulator line & return orifice was to small and could not return enough fuel back to the tank fast enough. The fuel pressure was at 90 psi to the injectors. I've up graded to after market fuel rails and a Fass boost referenced fuel pressure regulator. You can see the new componentry in action at the link to this video I recently posted. Also I switched to 1000 cc fuel injectors and lowered fuel pressure to 43 psi. Here is the link to the new video ...   https://www.youtube.com/watch?v=KzRU0tBjp4s
