Need some info on this don't know if they give me the wrong part or not.The Cummins book shows it has an o-ring on it . BTW this is for my 99. They were calling it the switch and in fact I was telling them it's a sensor.They told me it was the same thing. Is it? Cin

 

They call it a sensor here: http://www.dodgeram.org/tech/dsl/mt_...l_sys_comp.htm

 

I know that, does anyone have a picture to see whether or not they have the o-ring or not

 

I don't have a pic, but this is the part number on Geno's site. Oil Pressure SensorCummins3408428

 

I must have a cross referenced number

 

The 99-01 is a pressure sensor.
Yes O ring on the sensors and switches.

 

I also found this: https://www.dieseltruckresource.com/...oto=nextoldest

Confusing isn't it.........

 

Guess what guys I don't have an o-ring ooooh that makes me mad.And of course nothing is open today.That's my luck. So are they the same thing or not? I have only heard of sensors because of our 98 12v.

 

Use the old O ring.

 

Question is will it work without leaking? I think we're gonna have to try. Thank you all for all the help.Cin

 

Just go to your local ace hardware store and buy an o ring for it.

Probably run all of 50 cents.

 

That's what I was thinking about. thank you again for all the help.

 

Old o-ring will be just fine. If you're still paranoid a small bit of RTV on it.

 

Guess what guys it was wrong and there it is a sensor with an o-ring on it and it is bigger than the switch they are not the same thing. Switch cost 47.00 the sensor cost 222.00.

 

12v sensor cost the $47.00 (they were calling it a switch)it is a sensor. The 24v sensor cost $222.00.
