Hello,

I've just fitted a smiths oil pressure gauge and it seems to be working fine. 68lb on idle cold.
But I fitted the transparent pipe and noticed the oil doesn't go all the way to gauge, is this normal/Ok?
It seems to stop the last bit going up to the gauge on the dash.

Cheers for any insights.
Mark

over time you may notice that the air will bleed out of the tube when the car is hot and running. but again dont worry. its pressure in the pipe that the gauge uses

how? if it is you have a fault somewhere and it is leaking.

I was being impatient, after a while when the engine warmed up it eventually went all the way to the gauge.
Thank you for your replies.

I have always slackened the fixings at the gauge to bleed air out.  Seems to make the needle movement on the gauge smoother.

Absolutely right Unburn, air compresses making the needle "jerky" until the air is fully compressed by the oil pressure, oil does not compress so gives  a smoother needle, but having said that, once the pressure is up the needle pretty much doesn't move anyway
