Fuel Gauge Always Reading Empty

[leeperry]

I've got a 2014 Mustang V6 Performance Package with a manual transmission. Had it since new and put 149K trouble free miles on it. The gas gauge in the last six months had intermittently been going to empty, turning on the low fuel light, and the check engine light even when the tank is full. I've taken it to Ford who recommended that I replace the fuel level senders on the fuel pumps. Long story short, both senders and pumps were replaced, and the gauge still only works intermittently. They now say the fuel is not getting over to the passenger side of the tank because of a venting problem and I need to fill the tank slowly with the nozzle at a 45-degree angle to give air a better chance to escape or replace the fuel tank for Lord only knows how much money. Anybody got any ideas???

Check and see if you have a loose ground wire anywhere on the vehicle. My brother had a Toyota Camry automatic that kept slipping out of gear. Toyota couldn't figure out what the problem was because there was no code for it. He took it to a shop that specialized in vehicle electronics and they found the problem was a loose ground wire on the back of the stereo system. Of course it's not the same problem you're dealing with, but who knows? With everything you've been through it couldn't hurt.
