ok, here are the pics.
this is from the top of the enginehttp://www.engr.orst.edu/~wheeleza/three.jpg
closer to where it mounts up.http://www.engr.orst.edu/~wheeleza/two.jpg
this is the actual tee I installed.http://www.engr.orst.edu/~wheeleza/one.jpg
you can see that mine does have a slight leak, but it is so minor it is not even noticeable. you can also see where I scored the heck out of my oil filter getting it off.
I got a new filter wrench after that.
the oil temp sender won't work the same way as the pressure. you will have to tap the hole because oil has to flow around the sender (you can't add a tee). I don't know if there are any spare holes in the block or not.
I'm not entirely sure that you need the stock sender, which is on the end of the tee, but I kept it. the idiot light only goes off if the signal is grounded (which happens when you have no pressure), so that shouldn't happen if nothing is connected. however, I think the ECU might depend on the signal from the stock sender. like I said, I'm not really sure.
oh, the parts cost me about $14.
hope this helps.
