I have a carbon fiber dash in the car thus eliminating the stock cluster. How do I hook up a aftermarket gauge? What are the ohms? How do I check the ohms with having duel sending units?
Car= 1990 Subaru Legacy Turbo conversion
Walbro fuel pump/stock fuel tank/stock sending units
HELP???

The two senders are wired in series, so their combined resistance gives you an overall fuel level.
Check out this thread for the resistances

I don't know. You'll have to check the specs on various aftermarket gauges and see which guages have a resistance range that is similar to the stock.
Basically, you're looking for a gauge that responds to the following range
1.0 - 5 ohms when full, and
92 - 96 ohms when empty

This would likely work. I believe the bottom-most option would be the correct one.
