.............nut making sure the oil line does not move while tightening.
Thought mine didn't move, guess I was run. Knew I was wrong when after the engine was running I noticed a 1/2 cup of oil on the ground under the runningboard and in the cab - what a mess! Removed the Guage and re inserted the tube, made a mark on the tube this time and kept a close eye on it while I tightened the nut...no problems now
