I haven't got a picture of my inlet manifold but I'll use this:



I have hoses on all of those five spots. If I recall correctly, upper one is for the dump valve. However, the lowest one has an Y-piece, which has the other exit plugged off, and the other one goes to the fuel pressure regulator if I remember right? Is this wrong, as I remember there should be no T-piece on FPR hose? Is this standard wiring or some stuff that previous owner had done? Where should I put the boost pressure gauge hose then?
