4bar @ 800rpm idle, on new rb30det Oil pressure senders, blue v's yellow ???

[GDZ1LA]

is there any difference between blue and yellow oil pressure senders other than colour lol,

i am using a blue one on a freshly build rb30det it reads 4 bar at idle and 5 bar at 2000rpm, this is seriously high isnt it?, the gauge seams to be working correctly as is 0 when engine off, it takes about 15 seconds to build up the 4 bar pressure,

i run no oil squiters and a std rb30e 1.5mm head oil feed,

i am using a rb25de oil pump,

not that this awsome pressure is a problem? i just want to know if its this sender?

i have blue and yellow ones

a blue one is installed (i think it was off a rb20de)

are they calibrated different? my dash is a r32 gts,

any one else had that pressure on a rebuilt engine?

i dont uderstand why nissan would make blue and yellow other than different claabration>?
