I have a 97 xp that I'm currently doing maintenance on. I would like to replace the old clear (now brownish in color) oil lines from the oil tanks to the motor and oil pump. I believe they are 12mm ID. I can't seem to find any near that size in fuel lines at 2 of my lawn mower shops. The closest thing I can find is clear vinyl tubing at lowes or ace hardware. Are these lines ok to use? I already replaced the smaller oil injection lines with 3/32 tygon fuel lines.
