He no longer needs help, the fix is 2 minutes under the hood.

The problem is acquiring the part.

Stemming from sourcing different components from different cars (Legacy GT motor, STi everything else) a fatal design flaw occurred... it ended up without a fuel pressure regulator. The STi unit is on the fuel rail, but the Legacy one is actually on the return line itself at the strut tower. Having looked at pictures of STi engine bays for guidance, we figured that nothing more than the fuel dampeners went on those lines and left them unimpeded. Oops.

Unfortunately it looks like the part is dealer-only, and being that it has hose hookups at both the outlet AND inlet, nothing from any other car I've seen (or that we looked at at O'Reilly) would work. I suggested cutting off part of a fuel rail with the regulator in order to provide an input tube, but that's in no way, shape, or form ideal.
