Here are the pictures of the finished installation of the pump voltage unit and the high-flow strainer filter.






The strainer is made from strainer grade brass screen and has been implemented with a machined aluminum pickup with an AN-10 line size to feed the pump with less restriction than the factory plastic unit and small line. Seams are soldered to avoid dirt getting past the screen. The piece turned out really well I think.

Notice the boost pressure line to the pump voltage module. There is a 30 amp power relay in the battery box which is fired by the factory fuel pump relay. In turn, high current lines run to the voltage unit and then back directly to the pump. 12 gauge wire was used throughout.

If you are running a big pump off of the factory lines you are not getting the full potential out of your pump. I have a 1-2 volt voltage drop off of the factory lines. You say, 1 to 2 volts isn't much, but in actuality it is, because it is a significant percentage of the voltage the pump runs on. I can now step fuel pump voltage up on boost. The unit allows the pump to run just about normal voltage when in vacuum...that's a large portion of the time when the car runs. Pull out the vacuum and the voltage steps up, then swing into boost and the voltage is stepped further. The rate of increase is adjustable.
