Looks like the assembly includes the filter regulator. So Kinda no brainer to get the whole shebang if I am doing any of it. So now its a question of which chinese part is better Spectra at $50, USMotor ? $82, Denso $129, Delphi $145 The Spectra is a closeout - don't know the original price. Anybody got input to any of these better or any junk? @Tooljunkie
