Fuel Problem?

1994 mustang gt

When the fuel level is about/around half a tank(that's what it shows) when you take a right turn the car will die until its level again and will start right back up. When you fill it all the way up it smells like fuel until it get around the half tank mark. When it's full the gauge shows way past "F" and I ran out of fuel on the quarter tank mark. Any suggestions?

Re: Fuel Problem?

Sounds like maybe your fuel level sensor in the tank is bad .

Evidently your fuel level sending unit in the tank needs to be replaced.
It also sounds like your fill tube connection and/or grommet is bad and needs to be replaced.


When you turn a corner the fuel is sloshed away from the fuel tank pickup, so therefore you lose pressure and the engine dies. There should be baffles in the tank to prevent that from happening, but they make have broken loose. Check them when you are replacing the sending unit.


While you are in there you may also want to go ahead and replace the fuel with a 190 lph pump to support any future mods you might do.

Pulled the tank and there is a hose that runs from the fuel pump to the bottom of the tank to some piping? Hose was broke fixed it. The gaskets around the fuel pump and fuel sensor was bad and cracked fixed them. Now she works just fine. Only problem is that every time I remove my fuel cap it has built up pressure and suggestions?

Re: Fuel Problem?

Some pressure may be normal, it vents through the charcoal canister on the left front frame rail so make sure it is connected and functioning.
