Oil pressure sender

[code7rpd]

I just started a rebuild on my 3.0 and could not break the oil pressure sending unit free. When I put pressure on it with a wrench the square block it sits on came loose so I took that and the unit out as one piece. Any suggestion on how to seperate the sender?

Also, when I pulled the motor I goofed and did not note two things:

1) There was a vacuum line coming into the engine coompartment from the firewall near the crusie control module - it came loose during the drop and I don't know where it goes - does it go the side of the airbox - I noticed a nipple facing the 1-3 cylinder bank.

2) The wire on the harness that connects to the oil temp sender on the oil breather housing - it came loose during the disassembly and I did not notice it until I pulled the wiring harnesses out. Anyone know what color wire connects to this sender?

Thanks - these are probably pretty basic and dumb questions but rest assured, since I am just beginning the rebuild there will be more to come !

Place the block in a vise and put a wrench on the sender. It takes a very thin wrench as pictured.

I need more info (maybe a picture) to id the hose.
The wiring is as follows:
Green/ red = oil pressure


Green / black = oil temp

Thanks Henry. The temp sender I was concerned with was the one on the oil breather housing. Any ideas on which wire connects? I am sure it will be the one left over that I did not make a note of but sinec it is a hard place to reach I just want to make sure I get it right the first time.

What is the wrench size (across the flat) to remove the oil pressure sender from a 1988 3.2 Carerra motor? I see the wrench in the photo, but when I bend a wrench, I want to bend the right size.

Thanks in advance, Tom

See the previous post for details.

You must be doing an 80 to 83 and the temp wire on the breather is part of the separate harness for the oxygen sensor lambda that connects to the chassis on the front of the engine, either a 6 or 12 wire coinnector depending on the year.

I am looking for the wrench size (across the flat) that I need for the sender.
