Most recent oil change I went to replace the oil sender but it wouldn't budge so I'll need a different tool, thinking open end crow foot (my standard open ends were too long to fit in there)

I went ahead and did the rest of the oil change anyway as I have since decided to order an OEM sender instead of the aftermarket one I got + I'll need to find a suitable tool to remove.

So question is can I replace the oil pressure sender without draining the new oil? Seems like it might pour out as it sits in the oil filter housing?

Sure thing. Just hurry up and screw it back in quick to stop the leak.lol
You are going to spill some but minimal amount if you are quick. O yeah  make sure you do it  while engine/oil is cold.

It won't leak that much out. I've done this before. I would recommend having an aftermarket oil pressure sender installed somewhere though. The oem unit is not very accurate and doesnt really give you a pressure value. An aftermarket one will be much more accurate.

Texasquest; the OEM P\N is MD092660 - when I ordered it said "in stock" so I hope it is still available.
Techboy; when I meant aftermarket I meant a parts store oil pressure sender (instead of OEM) - apparently per searches on this forum some of the parts store versions fail quickly.

Thanks all for the replies, just wasn't sure if I had to drain it all again to do this.

I understood what you meant, I was just making the suggestion of adding an actual aftermarket guage if you don't have one already b/c the stock gauge is not very accurate and doesnt give you a value. A simple Autometer gauge will tell you 60psi at a glance.
