Fuel gauge erratic ?
My 99 Expedition has had an erratic fuel gauge for several years. I replaced the fuel pump assembly (includes new fuel sender) with an Airtex unit. I still have an erratic fuel gauge. I also have a "check engine" code 452...." EVAP pressure sensor signal low". The truck runs great! Does anyone have any ideas what this could be? Thanks, Mark

What is erratic?
Good point. The gauge will indicate 1/4 tank, 15 minutes later it might go up to 3/4 of a tank. The next time you start up it will show 1/2 tank etc.The changes are very slow though. Mark
