Fuel gauge stops at three quarters full

When I fill up gas the fuel gauge only goes up to three quarters and stops. Does it mean my gas tank isn't filling all the way or is it a faulty fuel gauge? What's the solution? Thanks

Hello,

This sounds to me like it could be a faulty fuel sending unit. I have a link down below I like for you to go to.

Thanks for the response. The issue was with the gas gauge on the dashboard. All It needed was an adjustment.

Second question. How do I change the horn on 2009 Hyundai Elantra. Which voltage horn, how do I reach the horn, and how do I wire it? Thanks

Hello again,

I have included in the diagrams down below all the information that you requested. When it comes to picking horns though, if you don't want to go with a stock horn then it is pretty much up to your own personal taste. You can get a horn that sings"way down south in the land of dixie" like the General Lee from Dukes of Hazard, or one the goes "AUUUUUGA" like an old tyme 1918 car. The point is what ever makes you happy. Please let us know if there is anything else that we can help you with,

Thanks,
Alex
