Fuel line (connectors)
 

:confused:Hi there - 1990 F250 2x. does anyone know if the fuel lines from the fuel distributor to the fuel filter 3/8 or 5/16? The connectors are 3/8 for supply and 5/16 for return but when i called parts dept they said 3/8 connector could have a 5/16 line or vice versa. Thanks for any advice.
