   After the anxiety of ZERO pressure on my 1984 2l Spider’s Jaeger gauge at idle, or for that matter at 60mph on the highway, I replaced the 37 year old sender with this.
   It has an 18mm normal thickness backing nut, that a shorty wrench of normal thickness can turn to tightness.
   I plugged in the original wire, turned the key to red light ignition, the gauge’s needle jumped to maximum, and I fired up the engine; and to my glee the gauge then read about 70lbs.
   I am using 20-40 Valvoline non synthetic oil, with a bottle of Lucas oil additive, and drove it about 5 miles to a normal warming of the temperature gauge.
   At idle the pressure remained at about 70lbs, (1/2 way from 57 to 114) on the gauge, and did not drop down to 10lbs.
   My engine does eat, and leak some oil, but otherwise it runs very well.
   It is a relief to see the pressure reading now, at least indicating that the oil pump beats it’s old heart in an appropriate way.
   I hope my heart does so too.
