Its a 100 micron stainless aeromotive filter before the pump. I have a -8 fitting welded to the top of the tanks as im running a -8 return. Yes it -10 from the tank to the pump and then -10 to the front where it has a Y fitting and splits to two -8 lines going into both ends of the rail.Reign_Maker said:SD, that looks great... How many microns is that prefilter? Are you using a -10AN to the pump and an -8AN after the pump? Is your fuel return back to the top of the tank using the stock return?
