? Can you use a Digital dash fuel sender in an analog dash?

[87 WE2]

Quick question can you use a 0-120 ohm Digital dash fuel sender in an 0-90 ohm analog dash car? What are the affects if any? Thanks, Ed

Yes, you can use it, but the gas gage will stay buried on full until you get down to 3/4 tank or so, and then start dropping.... the closer you get to empty (0 ohms) the more accurate the gage will become.... but will always read high.... not really a good thing.... it will work, but it would be awful annoying to me....

90/120 = 3/4 tank actual (90/90 - gage reads full)
60/120 = 1/2 tank actual (60/90 - reads 2/3)
30/120 = 1/4 tank actual (30/90 - reads 1/3)
15/120 = 1/8 tank actual (15/90 - reads 1/6)
0/120 = walking, cussing.... (0/90 - reads empty....)
