I recently bought a 1991 Ford F150 that runs great except for one problem. When running off the front tank, everything is fine, but when running off the rear tank, the truck bogs down, and there is a noticeable whine coming from the tank. I believe I read that there is only one filter for the whole system, so is this probably the rear fuel pump going out, or could there be another cause?
