I just replaced my leaking fuel rail (billet tees and stock injector caps) with a billet fuel rail. There were 3 billet tees. One was fuel in, one was to fuel pressure gauge, and one fed the secondary billet fuel rail (Stage 2 RCC). The new primary billet rail only has 2 ports. I plumbed it as follows. Inlet from the pump on the left primary. Outlet of primary to inlet of secondary. This line has a tee to feed the fuel pressure gauge. Outlet of secondary rail to a Bosch unit which I assume is a pressure regulator as it has a vacuum line attached which leads to the bottom of the airbox. As far as I can see the only difference is the f.p. gauge is feed off the line from the primary rail to the secondary rail. Here's the symptom: when I turn on the key the fuel pressure reads 30psi (normal). When I start her the pressure goes to 100 (pegs the gauge). She doesn't run particularly well, won't rev past 4k and won't build boost. There are 2 vacuum lines on the bottom of the airbox: one goes to the tail of the bike and connects to a small black box that has a label 091906 0652 part 12223861 and a lot id number. The wiring from this module goes to the MT2 controller. The other line I already described (goes to the Bosch unit). The line that goes to the boost gauge is actually tee'd with the other line going to a throttle body. The other vaccum lines I see are all tee'd to the 4 throttle bodies and connect to a single line which feeds to what looks like a filter and tee'd off to a Suzuki component with the part number 15620-02F00. All I did was replace the stock rail (with billet inserts) with a billet rail. What the hell did I do wrong? Thanks,
