79 Midget low oil pressure warning light

[richard.arnold@juno.com (Richard D. Arnold)]

I've just replaced the oil pump in my '79 MIdget, along with the oil
pressure bypass spring.  I still get a flickering warning light on a
warmed through engine at anything less than 1500-1800 rpms.

I'm going to hook up a mechanical guage to it this afternoon and check
the pressure, but in the meantime, what are the odds that my sending unit
is bad?

Any other suggestions?

Thanks!
