So, I'm swapping out the non tractor gauges with tractor gauges that are graduated more towards our use. A water temp gauge that doesn't come off the peg until 160+ degrees and redlines at 250+ degrees is pretty hard to use. Likewise a 100psi oil pressure gauge instead of the nice clean symmetrical scale of an 80psi gauge. So, I ordered the oil pressure gauge from yesterdays Tractors and look what I have. I expected to simply screw oil the compression fitting from the old gauge and right back on the new one. The new gauge has a type of connection I've never seen before. What sort of a fitting am I missing?
