The oil pressure sending unit is located as shown below unless someone moved it to the top hole where plug number 2 is shown.
As stated, you just turn it with a wrench.
What is the gauge doing that has caused you to replace the sending unit? A oil pressure gauge is a twin to a fuel gauge so the gauge will tell you what is wrong with it.... So look at the chart below and see what your gauge is doing. If it reads like the top left picture then you are missing ohms input, so pull off the sending unit wire and ground it out... the gauge should go to 0 with the sender wire grounded. If it does this then the dash unit is working fine and you should replace the sender. If you purchase an aftermarket sender make sure you get one for a gauge and not for a car with dummy lights... Flaps like to sell the wrong sender to customers but they don't know that it'll cause a problem.

My oil pressure gauge needle jumps around for about a second then stops completely, the oil pressure gauge is brand new so i think the oil pressure sender is bad.

Do the test stated above to see if the gauge is working properly... if it is replace the sender. If it fails then the dash unit or a shorted wire is the problem. You'll just have to do the test.

Just above the oil filter .One other way to find out if it's the wire or the sender is pull the wire off the sender and have someone in the car looking at the gauge,key on, than ground the wire that you removed from the sender the gauge should move. If it does not than it could be a bad gauge or a bad wire if it does move than it will be the sender.
