So my oil lines are leaking BADLY...went to AutoZone and they tell me I have to take the old one off to be able to find out what size I need...I guess they come with different size fittings... But if I take the old one off I can't drive the truck to get to AutoZone...and we'll have to wait until they get them in cuz they don't keep them in stock... Any of y'all have any ideas??
