I think that I hooked up my FMU backwards.
 

boost goes to the nipple on top; the feed goes into the side, and the fitting on the bottom in the middle goes to my fuel rail-right? ???

Here's the symptoms: When my ---- fully spools, my engine stalls-like when you have a bad fuel filter; however, when I put check valves on the hose that runs from the top of the throttle body to that can thing, I runs fine, but my boost gauge then only shows vacuum. Maybe it's not the FMU being hooked up wrong,but it's pouring rain and I don't want to be on the side of the road.
Thanks

unless you have an adjustable fmu and took out your stock fpr, the fuel feed doesnt hook up to the fmu at all, the return does

if someone would be kind enough to tell me how and what to hook this thing up to. Mine did not come with instructions :-\

i think you should hook up the FMU after the fuel rail and the stock FPR, here's a diagram:

BTW, what do I splice into for the return line back to the tank?

Re:I think that I hooked up my FMU backwards.
 

you dont splice into anything....pull the line for the return off the fpr

Re:I think that I hooked up my FMU backwards.
 

ok, I take the line that comes from the fpr, put it into the side of the FMU; the fittnig at the bottom of the FMU then goes to where the FPR was going. Kind of like a missing link betwwen the FPR and where ever the line was heading.
