On July 19, 2001 the Ford Motor Company issued a fuel system gasoline recall regarding a damaged check valve in the fuel pump sender assembly of F-Series pickup trucks. The potential number of vehicles affected is 1,556,221, according to the recall notice.
The vehicles affected by this recall are 1990-1993 Ford F-Series pickup trucks equipped with dual fuel tanks. The recalled vehicles will have a 4.9, 5.0, 5.8 or 7.5-liter gasoline engine.
Vehicles affected can experience the transfer of fuel from one tank to the other due to a malfunction of the check valve in the fuel system. When fuel returns to the tank not being used, which is called cross flow, the non-operating tank capacity can be exceeded, which can cause fuel to run out past the filler cap and possibly create a fire hazard.
Ford has extended the warranty for possible fuel cross flow to 12 years or 150,000 miles from the start date of the warranty, whichever comes first. Dealers will repair the fuel cross flow condition at no charge.
