Is my float thing messed up or something, is that why it is reading funny?

float has a hole in it so it is full of gas and sinks to the bottom of the tank. as for the gunk thing figure out your MPG and just figure out your rough miles per tank with 18 gallons of gas.

Well the gauge "works" because when I fill up, it moves to full, and tracks all the way to empty, and even triggers the light when it is getting "low". If i was getting about 180 miles from about 12 gallons, that is roughly 15mpg. So if i do 14mpg*18gallons=252 miles before I should think about filling up, and that should give me a few gallons left once I fill up.

Not worth it to try to fix since I have no experience at all with anything fuel related in my xj, so as long as there is no chance I have a smaller tank, I am going to take her to 250 miles with a 5gal. can in the back lol
