help needed: want to fix the gas gauge once and for all

Probably like most, I've been runnin with an inop fuel gauge for a long long time on my 69 dart. Well the wife is driving it near daily now since we moved to Hawaii and I also have to get it through the state safety inspection so its a must fix now.

Following a troubleshooting guide from this link
http://www.moparfins.com/repairs/fuel_gauge_repair/fuel_gauge_repair.htm

All the components seem to work

Voltage limiter: Ground the wire (on gas and temp sending units seperately) got pulsating test light and the needles started to climb slowly

wires: multimeter gave me a good solid tone when I checked the wire for continuity from the wire connector at the tank to the female end of the pin connector that plugs into the circuit bord.

sending unit: putting out 75-76 ohms (don't have a 0-100 setting but use 200ohm setting)

1) what am I missing?
2) what else should I check
3) if I'm using the 200ohm setting, do I have to divide the reading in half cause 35ohms would be about right for half a tank which is what I think is in there

additional info: bout a yr ago I bypassed the amp gauge. Apart from that I've done nothing with the wiring. I'm the 2nd owner and have had it for 25yrs so its unmolested.

Greatly appreciate any assistance. Got less than a week before my temp registration runs out for HI so I gotta get this fixed this week
