What's wrong, in plain English
On these trucks, which are built with gasoline engines and have two separate fuel tanks, the rear tank's fuel pump may not transfer an adequate amount of fuel over to the front tank. Because of this, the front tank may not receive enough fuel to keep the engine running properly, and the engine can stall while the truck is being driven.
