I have a 2015 Elantra and my boyfriend went to fill up my tank (my gas light was on at this point) and it stopped filling after about 2 gallons and started to overflow when he tried to continue pumping. I started my car back up and it said I only had a little less than half a tank full. What's the problem? I've already had other problems with this car, it seems never ending ??

Hard to refuel
(Overflow during refueling)
1) Inspect the fuel filler hose/pipe
· Pinched, kinked or blocked?
· Filler hose is torn
2) Inspect the fuel tank vapor vent hose between the EVAP. canister and air
filter
3) Check the EVAP. canister

Is this general information or was this lifted from a Hyundai manual for the Elantra?

Just to add, it could be electrical in nature. Perhaps the sending unit is sending false/bad information to the gauge or the gauge itself you have a problem.

Service Manual


You are right it could be the Fuel Level Sensor located in the gas tank, the sending unit, the gauge, etc.. I figured start of with the easy and work toward the harder.


One way to troubleshoot is to put a can of gas in the back and if you can drive more than 60~70 miles after the "gas light" comes on, you know it is something electrical.
