I just had to drop the gas tank on it because my stupid butt went and accidentally but diesel in it so for it to run again that had to be drained out of it. Besides replacing the file filter, that's all I did to it and it's running again now. However, now I'm hearing and feeling this new sound that's coming from underneath the car when I'm driving. Now I haven't driven it far at all cause of this, don't want to mess up anything so have only gone a few blocks then parked it back at home. I don't know what it is, but it seems to be coming from the front end of the car and like from the center underneath area, and kind of seems like a possible rubbing of something. Any idea what it could be and how to fix it?

It sounds like the disc brake dust shield is rubbing on the rotor. To be sure lift the front of the vehicle and spin both front tires, this guide can help:

Can you please shoot a quick video with your phone so we can hear the noise? That would be great. You can upload it here with your response.

We just had to drop our gas tank to get diesel fuel out of it and we got it running. Now, every time we've gone to put gas into it, the pump keeps stopping just after every few cents and once we do get the gas in it finally you can hear and fill like air being forced out of where the gas pump goes to fill it up. What could be causing this? Did we do something or hook something up backwards possibly?
