99 yukon oil pressure gauge

[Tomstowe]

our oil pressure gauge show fluctuation of oil pressure. we have a new sending unit. oil pressure is constant by mechanical gauge. any one seen this and is there a way to fix the dash gauge?

Mine fluctuates a lot, but from what I see it's just normal.

so you ate saying that the mech gauge remains constant at a specific speed but dash wanders at the same speed? or at any speed the mech dial stays still and the dash one wanders?

 

[SunlitComet]

what are the pressure readings you are getting on both at any given speed btw?

 

[willua11]

42-44 at highway speed when hot. 20-25 at idle when hot.

 

[SunlitComet]

well no problems with those number right now.
