Here's a write-up of a Bosch 044 In-Tank:

Need more base fuel rail pressure, spend $115 and wire in the Walbro 255 in-line.
Not, SR related; I'm using all -6 AN Lines, Walbro 255 In-Tank that feeds an In-Line Walbro directly to an In-Line Filter and then to the rail and 680cc Injectors for my 1JZ Setup.
