I need help!   Rebuilding a 1982 FXRS Harley,almost done,but have a prob. Oil pressure is there,not sure if is flowing back to tank. There are three tubes on the bottom of oil tank,I know the supply is correct...question is,does it matter where return line and vent go? I mean,they both return to tank,would it matter which position they are in?  I do not know which is which...easy enough to find out,yeah,am being lazy,but don't want to go through the oily mess if I do not have too!!And the prices these days if I waste some!!  LOL!! Thanks for any replies!!
