why can't I switch from front fuel tank to rear fuel tank?
Typically, the selector valve on the frame just below the driver's seat has failed. I've been looking for a good aftermarket replacement for my '87 F-250 some time now but fear that I will have to bite the bullet and change out all of the OEM stuff - wiring and all.
AC Delco # U7001 O'Rielys web site I hope that it the one you are looking for.
If it's diesel, it could the selector valve, the fuse or the switch on the dash. If gas, could be the fuel pump/sending unit.
