    I was talking about 45psi fuel pressure just so you know. Not boost.
    My dual pump setup has one in the normal spot and the other is in the rear of the tank. Its not really any problem at all because its not daily driven. Just cant run or brake hard with less than half a tank.

    Some people have had luck with Walbro's some have not. My car it whines like hell after long trips while on my wife's SRT-4 it does not. My pump isn't even that old nor have I ran the car hard.

    Walbro's are really our only drop in option unfortunately but they work besides some failing sooner then others. I am going to replace mine again eventually before it craps out.

    Mine Walbro had 8,000 miles on it and I think it's mostly caused by me running the tank too low and letting the light come on. I was in Peoria with my g/f and driving back to her school when out of nowhere I couldn't hit 0psi and my wideband was reading 17.8-18.0 everytime I hit above -10 vac. I finally got to a safe place to park and look under the hood and my fuel pressure gauge on the rail was reading 17-20psi. I just had enough fuel pressure to drive at 60-70mph idling down the road for 151 miles.

    Let's see now. I no longer run a Walbo 255 pump and never did the fuel pump rewire. The car has a lot of fuel and runs pig rich on the dyno down low.
    My current setup is the following.
    -RC 750CC Injectors
    -Boomba Fuel Rail with (-8 Feed)
    -Returnline (-4 Return)
    -Aeromotive External Fuel Pump -8 Inlet/Outlet
    -Russell's Inline Fuel Filter
    -PTP Queasy
    -3/8" I believe Fuel Line for my pickup inside the canister.

    Siemens 888/1025 @ 58 psi static
    Return line
    255 walbro
    bottleneck mod
    rewire
    I went with the bigger injectors because i run E85.With the E1 holding 21 psi at 6500 the injector duty cycle is 73%
