noisy injectors?

[sinister polo]

hi all recently fitted a set of 250cc injectors, 65mm pulley and a sns type chip to the ecu.
i have noticed when the cars running they seem to be realy loud, as in a clicking noise, you can feel it when you touch them aswell!

when i fitted them i used a spare fuel rail i had of my nz engine so im wondering if this limiting the amount of fuel, or could be time for a new fuel pump?

they are quite noisy anyway.  the fuel rail is the same anyway.
