I'm on the verge of selling this thing. 95 f250 w/ 182k mi. having serious issues. Starting w/ one fuel guage failing then the other, then having back pressure when filling tank (would only fill about half way). Then it died on me and the dealer told me the switchover valve went. Shortly after that it would stall when on a decline or incline. Now it will start fine but will stall after a few minutes then I'll have to let it sit for a while or it won't start. Now since the gauges aren't working of course I ran one tank dry twice. Is it possible there's just sediment kicking up and that's why it's stalling? I'm at a loss and can't find anyone who's heard of such an issue. I really don't want to sell it but frankly I'm tired of putting my hands on it. Any suggestions for this issue is much appreciated. Thanks.

 

Could be a fuel pump issue, check your fuel pressure using the schrader valve on the side of the fuel bowl...

 

After all that mess it turned out to be the CPS HA! Rookie mistake. Still no gauges though. Are there common problems with the wiring for the selector valve? I know both sending units are wired to it.
