I have an 1993 F250 with 5.8L. I'm getting false cues that the tank is out of gas and the truck chugs. Switch tanks and it runs ok for a while then happens again. Switch back and I'm ok for a while. I changed the filters and still have the problem. ???

I have a 1992 F150 with duel tanks and when I use the rear tank the idle goes rough by that I mean stall then run, but when I switch to the front tank the problem diminishes a little but still does it. The truck runs well enough useing the first tank but I would like to have use of the second tank as well. I did replace the fuel pump in the second tank and there was no diffrence. Please help.....

what is your fuel pressure like try on the first tank then try it on the second.

Hi, it's me again. I replaced the coil like one of the earlier users and still no diffrence. Does anyone think this could be a ecu problem or a throttle position sensor.
