so on my other thread which has apparently gone dead i had a pressure problem. i checked the pressure at the filter and had high 40's for idle and 75 at about 2000...which seems normal from my research.
but my gauge in the truck still does different things. the part that worries me is that around 1250 rpms it almost always goes to normal and then falls off. but when its started cold it stays normal until it warms up then drops off.
so basically i want to check what it says at the sending unit location with my mechanical so i can start to panic or be relieved, also i need to know where it is so i can change it if it needs changing either way.
i've seen the diagram of the engine showing where everything is but im basically retarded when it comes to this it seems and have no idea what to look for. so a picture would really help me out.
i dont know what to look for because everything is covered in oil and black so a picture would be amazing. hopefully someone can help me out.
btw i did search for this for quite a long while over the last few days.
thanks in advance
Dont have a pic but I will try to explain. First off go power wash under the hood and get everything you possibly can, this will make things much easier to see let alone work on. Drivers side of engine behind rear of your injector pump is the oil sensor you are looking for, you may have to remove loosen the return spring bracket or the bracket supportting the pump cant remember but its a very tight fit between the pump and block. There is a speacial socket for removing the sensor but I used a wrench or a pair of good channel locks cant remember which (5 yrs ago ). Hope this helps ya
I replaced mine abot 6 months ago. NO pic sorry I ended up braeking it on removal, got a new one from cummins cause for this item I didn't trust a zone. Follow the oil feed line from the vacuum pump, up above it is the oil psi sender. As the other gent said, below the P7100. Is rather difficult to access. I think the service manual tells you to remove it when replacing the power steering pump as you can easily fowl a wrench on the sender when accessing the Power steering pump mount. IT is all rather tight up in that area.
With my NEW oil pump ( cummins 24v pump - made in cina) I run a steady indicated 45 psi, so new pump keeps oil psi releaf valve continously working

i did get under the hood and believe i found the elusive oil sending unit...oh but wait!, not only did i find it, i captured it on digital photography...I WIN!
here it is for anyone that reads this and is wondering the same thing i was wondering...
i have a slew of problems cropping up left and right, time for another thread.
Got the sending unit on and all is well...checked the pressure with a mechanical gauge and it was textbook so that was a HUUUGE sigh of relief for me. Thanks for the help guys. Also for anyone else that would see this you need a 1-1/16" deep well socket and various extensions to get it off and on. I don't recommended trying to twist on the flat plastic part with pliers or vise grips...you may just break the sending unit as I may or may not have found out.
