i've just had all of the boost pipes off & found that the hose on the actuator was split, i've replaced it & reinstalled all the boost pipes but the boost gauge & dump valve are still not working???

does any1 know if the problem is because this dump valve is off an s14, is the spring too hard for 7psi to move?
