Alright, I sound like a complete morron asking this question. But when I took my motor out, rebuilt it, and put it back in, I didn't note which ports on the VORTEC FMU were fuel in and fuel out to the regulator. A little help for a dumbass in need.

 

C'mon, someone has to know, just go look at your own FMU.... it would be a huge help. Thanks.
