Gas gage flip out
It won't be anywhere near the same... if you look at aftermarket fuel gauges, Ford uses a sender that reads empty/full 73/10 ohms... while others are 240/33, 0/30 (opposite direction), 0/90, etc... they didn't standardize on it at ALL. You'll either have to retrofit a international sender into your new tank, or buy an aftermarket fuel gauge made for a Ford sender. From what you describe, with it staying full for a long time and then dropping quickly to 1/4 and then staying there, I'd bet your gauge is probably made for the 240/33 range, while your Ford tank is 73/10. If this is the case, you could make it a LITTLE more accurate by buying a 20 or 25 ohm ceramic resistor from Radio Shack and putting that in-line with your sender wire... that would move it to a 93/30 range, which means it would read close at full tank, but still bottom out at about 1/4 tank.
