Oil Sending unit?

[denroy]

I've got a oil leak in the back left hand side of the motor. Right below number 3. Looks like an oil sending unit. If it is any helpful tips as to how to get that little bugger out of there?

On the rear side of the motor to the left of the exhaust manifold is the pressure sending unit. The level sending unit is below and to the right of that.

The pressure sender is a common leak and an easy fix. Much easier if you have a lift.
