do you still have the supply line? see if it has the same female end on both ends of it...if so, then just unscrew the male fitting off the top of the turbo and go find a match...should be the same if its anything like mine....turbo feed is on the driver's side of the block...1/4 or maybe 3/8 inch pipe threads if i remember correctly...buy a brass tee with three females, plug up one and use the other for the turbo feed...you'll have a spare port for a mechanical oil gauge later...
