Oil Pressure Sending Unit Size


Recommended Posts

So my autometer oil pressure gauge is all wired up, however the only thing I need to know is what is the size of the oil pressure sending unit ? I need to get a fitting that will go in there to complete my gauge install. I've looked all over and had no luck. Thanks


Its an 03 Silverado SS 6.0L AWD.

is it the sending unit that is inside the engine bay and close to the firewall? if so i changed mine and i can look what size socket i used


Yes Sir, I know the socket size, however, there is a threaded fitting that goes inside the oil pressure sending unit that needs to be hooked up to the autometer tubing for it to work.


I have on on my chevelle BBC but I am no help cause i am not home sorry. Can you take it down to the store and match it up??


I guess , but that means I would have to remove the entire sending unti, not just the sensor.
