Oil pressure gauage/ Ford Ranger

Initially when the key is turned to "run", the oil pressure gauge (engine not running at this time) jumps up, ~ 3/16ths of an inch.
Upon start up, engine now running, there is no movement on the oil pressure
gauge needle. After engine warms up, approx 4 minutes, the gauge indicates ~60 %, and remains there. The is no modulation from rev-ing the engine.
Question is, should I replaced the transducer, or the gauge, both appear to be a very difficult task.
The problem is in a 1999 Ford Ranger XLT, V6, 4.0.
Would appreciate hearing from all parties experiencing like problems.
Thank You,
R. Maniag

The oil pressure gauge on your truck is a FAKE. Ford did that with all its trucks in the late '80s, and the transition was complete on passenger cars that had oil pressure gauges by the mid-'90s. You have a snap switch sender down by the oil filter that sends a signal to the "gauge", and just like an idiot light, only tells you that the engine has SOME oil pressure. Unlike an idiot light though, it doesn't attract your attention when oil pressure is lost. See: http://www.sfuller.net/projects/cobra/oilgauge /
Those instructions are for a Mustang, but yours is the same deal. Check a couple of Ford truck forums for drivers that have found out about the bogus gauge and done mods to make it a REAL OP gauge.
