Fuel Tank Switching?
Is there a method of determining the valve that switches between fuel tanks on a 91 E150 Econoline W/ 5.0 FE, is functioning properly.
Currently, I only run on the rear tank, when I flip to the front tank, the fuel gauge cuts to enpty as if engines off. I've tried running on it anyway, assuming the gauge was faulty, but not sure how much fuel was in it, I switched back, only to learn it was drawing fuel from the rear all along. WTF?
Any advise would be hightly appreciated.
