I need to know if my 99 7.3 psd has an inline fuel filter... i have changed the water bowl filter but I'm wondering if it has one on the fuel line?

 

Not that I know of, just the one in the middle of the engine.

 

The 'in tank' fuelmodulehas cylinder shaped micro filters inside the module body.. Removable/cleanable.. They sometimes get over lookedand can plug restricting flow/volume/pressure, more so on the highermileage trucks, or that have had less then quality fuel put through the system..If just anormal filter change/interval, and no performance issues, nothing to be concerned with..
