Engine Mechanical problem
1988 GMC S15 6 cyl Four Wheel Drive Automatic 333333 miles

The trucks oil filter is on the drivers side fenderwell and the lines run from it down under to right beside the oil pan. I have a bad leak at the lower connection. How do you get to that nut to tighten it. Do I need to pull the unit its connected to out to get to it. Or is there a special wrench to get there. Thank you
