How do I expand the oil return tubes?

I just did mine. There is an easier way to expand the tubes: hold the smaller diameter tube with a pair of channel locks, and place a crescent wrench over the smaller diameter tube, tighten the crescent only enough to close it to the diameter of the smaller tube, and then slide ot over to the edge of the larger tube. While having an assitant apply mild pressure on the channel locks to keep the small end seated in the engine case, take a soft hammer and hit the crescent wrench, causing the wrench to hit the edge of the large tube. It will move with each tap very easily, The rubber o-rings want to grab the tube if you just try to stretch the tube with force- they will exert considerable traction and prevent the tube from expanding. It you do this tap method, it takes only light taps to break the o-rings' grip and let the tube expand. All tubes went in in less than 1 minute each with this method, and no damage to the tubes, either.
