In a word YES, :lol:
Have you assembled Chris's board and fitted it to the binnacle?
If so you need to supply +12V to the +ve terminal of the board, -ve to the ground terminal and then connect a 100ohm resistor between the coolant temp sensor terminal and ground.
This will test your temp gauge, it should put the needle somewhere near the LED on the gauge.
Then move the 100 ohm resistor to the between the fuel level sender terminal and ground.
This should put your fuel gauge somewhere around the 1/4 to 1/2 full mark.

If you havn't fitted the board yet, you need to supply the positive side of the gauge with +10V (not12V) then connect the 100 ohm resistor between the sender side of the gauge and -ve of your 10v supply.
Chris's board has a 10v regulator on it which makes it easier to test the gauges after fitting the board.
