I have an "02" 7.3 that I want to install A oil pressure gauge. Dose anyone know where I can tap into an oil galley? My oil filter houseing dosen't have A plug where there is sapposed to be one and the Stock gauge location is not pipe thread. Neather is the plug next to the stock gauge. I've been to A couple of parts supplyers but, no one has A clue on what type of treads are in those locations. This is the last gauge to install and I would like to get it going. It came with 1/8" pipe thread fittings! Sam

 

You talking low pressure oil or high pressure oil?

Low pressure has only about 1 place, which is where the sensor is on top the resivour.

If you want a High pressure oil guage, this is what I have and it works great.

Yeah I knew it wasn't fuel pressure.. That link was for high pressure oil..

 

So Then if I can only use the top of the resivare, What kind of thread is that plug there? I know it's not pipe thread witch is what they use for oil pressure gauges. I'm useing Auto Meter Sport Comp Ultra Light Gauges.

PS I can't believe that there isen't A plug somewhere eltz on the block that has oil pressure running at it! Sam LOL

 

The plug on the top of the HPO res is a O ring boss AN-4 IIRC, it could be a -6 but I am 90% sure its a -4. Any hose shop worth the name will have those parts.

Also there is a plug down by the oil filter, every truck has it, both on the block and on the filter/cooler ***...

I'll see if I can dig up a pic or two.

 

Here is the HPO res location... You can see the fitting below the 90*



Here is the one on the oil filter/cooler block... Its there, trust me...




I dont have one of the block location... I will have to do some more digging or take a pic off one of the blocks in my shop this weekend.

 

Yes thanks for the information. My oil filter wasen't drilled and taped. I looked there right after I found your pics on Another post. LOL I went to A industrial warhouse. Monday and found some fittings that worked. Not quite the same has your pic but close. If I have time I'll take A pic and post it this weekend.
