ever elusive valve ?
I have a 1990 f250 with a 460 and dual tanks. The rear tank is not working. The pump is running strong. They are saying it is a problem with the tank selector valve located on the frame rail. I don't see it anywhere. Where is this mystery valve located?

If the rear tank pumps runs then you have a bad Fuel Delivery Module (FDM) in the front tank.

Well.. "They" are totally wrong because your trucks doesn't have a tank selector valve. If the pump runs then is it possible there isn't enough fuel in the tank? If not then there must be something wrong with the pump.

Some places will sell you just the pump but you do not want that.
What you want and most just replace the FDM (Fuel Delivery Module):
The FDM called by the wrong name in the below item:
Some do go a and buy the hanger and the FDM and gauge sender as one unit but that cost a lot more.
