Sounds like you have the wrong sending unit.   They are externally 
identical, but internally quite different.   The one for an idiot light is an on/off 
switch.   That's why it sends your gauge from zero to pegged.   The one for 
a gauge is linear in its output.

Trot on down to your local parts store and you'll find what you need for 
about twelve bucks.   Just tell 'em it's for a '72 Mustang with an oil 
pressure GAUGE and not a light. :>)
