Hey all, so I've been having some problems with my tank sender/fuel tank since I got the car. It's really odd...

First off the fuel gauge lies to me, the needle will now get to the "R" and once it's there the car is literally running out of gas, no reserve light comes on, no warning.

Then on top of that, I filled up my tank today which should be like 17 gallons and it only took 13 gallons to fill it up, when it was getting close to the "R" which means it was almost out of gas... What's going on here????
