Haha the great oil debate! Yota, where is the fuel filter, I was just thinking the same thing! Don't have an FSM for the 85'.....yet. I have an unused port on the blue capped vacuum solenoid. A vacuum line runs off the white part of this solenoid and connects to the fuel pressure regulator one the fuel rail. Is there a place where this should be hooked up, because if the fuel pressure is off it could cause a lean condition. There is an unused plug on the right side of the engine and two sheathed wires that have been cut which probably had a plug on then. The plug has the ND logo and the number 3, any ideas? Anyone with an 85' FSM?
