My lines were reversed and for about 15 years they ran fine. I found another truck and another and the lines were as described above. Top of filter to rear hole etc. I reversed mine to what I thought was the right way and nothing changed except I found my oil pressure dropped at idle! I even had the diagram of the routing sent via one of these posts and it proved mine was wrong for all those years. When I pulled the pan I noted the routing from the pump to the op gauge and the filter. So what happens is the oil is pumped thru the filter (not a high percentage however) and is dumped via the bottom of the cannister to the front port and into the oil pan. Still can't figure what happened to cause the drop in oil pressure, though. Nothing else was touched. | | |
