I've got a 6mge with the oil pressure guage showing low pressure at all times, even though the oil pressure is actually good (checked with a pressure guage comparing to spec). I've figured out a potential cause for this is that the oil pressure sending unit on the motor atm is for a digital dash, but I need one for the analog dash. Am I correct to assume a 5m oil pressure sender directly fits onto a 6m? And any chance anyone knows what the Toyota part number for it is? Thanks!
