Question about 1989 Ford F 250
Filled up the rear tank and put about 1/3 in the front. Selected the rear tank for use (driving back and forth to work) I noticed that the rear tank never got below Full, but the front tank was about empty! I also noticed that when I would drive at freeway speeds, (above 60) with the selector in the rear tank position, old Betsy would spit and try to stall. I would switch to the front tank and all would be well at higher freeway speeds. It runs fiine at about 55 in the rear tank position. So I guess my question is: Is it the low pressure pump in the rear tank or the tank switch.....or both?
Hi your symptoms suggest that you have slight blockage either in fuel line or most likely at point where rear tank fuel line enters the switch over reason ? you say runs ok on rear tank at 55mph? but when demand for more fuel / speed above that pump /engine cannot deliver ? due to narrowing of fuel line (tuberculation) so check flow from r/tank and for any debri inside?
