Factory senders make all the difference
Got the tank down into my "ruh roh" level
Went to the station and filled it up 14.9 gallons.
My tank has a dent and only holds about 17.5 gallons (most i ever got in it when completely empty)
14.9 / 17.5 = 0.85
1 - 0.85 = 0.15 (gives decimal equivalent of the fuel left in the tank)
0.15 x 8 = 1.2 (that is 1.2 eigths of a tank)
Even if you use 18 gallons
14.9 / 18 = 0.83
1 - 0.83 = 0.17 (gives decimal equivalent of the per entage of fuel left in the tank)
0.17 x 8 = 1.38 (that is 1.36 eigths of a tank)
Here is where my stock 67 guage, stock mechanical IVR, stock wiring, and later (supercedes number) oem fuel sender reads.
Those are my "outdoor"shoes!
