General Tech Installing New Oil Pressure Gauge

[65_BRG_Sprite]

In the process of installing a non-original oil pressure gauge that Moss sells. Should I prime the tubing with oil prior to making the final connection? Concerned with an air bubble that will affect the accuracy of the pressure reading.

I prime or bleed. Be sure that there is a seal at the connection to the dial...unless it is an olive hose.

Showing my ignorance- "olive hose"? There is a ferrule to be inserted over the tubing which is then compressed by a capturing nut.

You really don't need to bleed the line. The pressure will be the same throughout, whether it contains air, oil, or anything else.

+1 to Steve's comments. You do not need to bleed the air out of the oil pressure line. Pressure is pressure.

Olive is another term for ferrel. Your choice on the bleeding of the line...looks like you have options?
