My 1987 300zx non-turbo automatic has a weird quirk... when the gas
hits 3/4 tank, the primary needle quickly drops to 1/4. Then it'll drop
to E, then past E to wherever it stops. Thing is, it still has that
missing half-tank.
Until recently, the secondary quarter-tank needle still worked... When
I was really running into a quarter-tank, the orange indicator dropped
down into view. However, that just stopped working. Now I don't know
when I'm truly running low until the fuel light comes on. God forbid
that stop working, too...
Is it possible I have a faulty fuel sensor? Does anyone know how I can
fix this?

Likely is the problem.

Replace the fuel sending unit. It's in the tank and there is a access panel
for this in the hatch area.
