If you have the original level controller, that indicates a gauge
problem.  Check by unplugging the sender connector from the pressure
tank in the engine room.  If you get blinking light and the needle
pegs, you have the standard controller for your year, and the
blinking light is a gauge artifact.*  If you get blinking light and
the gauge does not peg, then see Robert Stewart's post.  My best
guess is you have the newer controller which does not peg the gauge.

*There's a 10 uF 16v capacitor inside the gauge that controls how
long it blinks.  The cap gets leaky...

Yrs,
