1993 F350 Non - Turbo Knocking

Hello Everyone!

Yesterday I replaced the fuel filter on 1993 F350 7.3 non-turbo.

Today, I was going about 65mph when i heard a loud knock develop in the motor.
The truck now idles very rough too.

Considering I went to town to top off the fuel, could that be a factor?

In reading on here, I see a lot of reference to injectors being the potential problem. But other than general maintenance I really don't know much about diesel engines to diagnose the issue any further.

Any input would be great! Thanks
