Dwight,
the BLACK wire should go to the chassis earth: check that this is so
with a test lamp or voltmeter.
He should be connected to the mounting flange of the fuel sender unit
to earth the fuel tank i.e. E for EARTH.
The YELLOW wire should go to the fuel gauge: check that this is so by
earthing it, with the ignition on, the gauge should go to very full.
He should be connected to the G terminal i.e. G for GAUGE.
The typical result of having the wires frack to bunt, is a resistive
earth (thru the sender reistor coil) to a gauge wire which is
connected to an unreliable earth on the fuel tank metal: could read
anything!!!
However, trust me, your wife will not be collecting any insurance
money on this point UNLESS you use a naked flame to check the fuel
level with the cap off!
BTW, I measured the fuel sender the other day for another lister:
empty should be approx. 14 ohm, full should be approx. 95 ohm.

Subject: Fuel sending unit ???
All,
I have a brand new fuel sending unit from Nissan, and it has the
Letters
"G" and "E" under the terminal posts. Which is which? I did have the
black
cable that goes to the chassis ground on "E" thinking it meant "Earth"
like on
the alternator. But, I'm thinking "G" means "Ground". If so, what's
the "E"
stand for, and does the yellow wire connect to it that runs to the
"Tank" side
of the fuel guage. Both orientations provide kooky results, but I'm
also
afraid of having it backwards, turning the key, and having my wife
collect on
my insurance policy. Thanks.
