I used 87 in both tanks, and the tank Im on isn't gone yet I was estimating 120ish for this tank.. Im at 97.9 miles so far on this tank, and I have a hair over a quarter left on the gauge. Both tanks were filled to full at my usual gas station, with lucas fuel additive each time (I like to stay consistant)
@johnm10 I would imagine the gauge is working properly, but cant positively confirm it until I go to fill up again. I hope I didn't damage the sending unit I was even careful putting everything back together. I kinda broke my rear deck lit taking that out so Im trying to be more gentle now :/
