I'd tend to agree with firecatsnopro. You are not going to get an injector to atomize fuel very well at 3-10 psi!!

I think it was referring to the pressure that the pump is sucking the fuel out of the tank at(between smartvalve and pump itself). Could be wrong but I copied it out of the perf manual. The injectors/fuel rail does run higher, on my 98 ZR 600 I believe it was in the 35-40 psi range. Sound right?

I had a 99 zl 600 efi was set at 38.8
