Ford Full-Size F-Series In-Tank DIESEL ENGINES ONLY sending unit "Funnel" fuel filter. This in-tank fuel filter has a 3/8" I.D. diameter. Ford did offer a 1/2" fuel pickup tube on a limited number sending units in the F-Series trucks so please verify your sending unit has a 3/8" O.D. diesel fuel pickup tube. This is not the correct in-tank fuel filter for Ford trucks with GAS engines.
