The racors will filter any fuel added to the canister after the filter element is installed.

Depending on the level of fuel in the tanks fuel may or may not flow into the filters by gravity. Lift pumps often will not pull fuel through a mostly empty racor so some means of preefilling them is necessary. I used the jug of fuel method.

The on engine filter is usually after the lift lump on the pressure side so working the lift pump while venting will fill it. some engines will start and run with the on engine filter empty and self prime.

n.b. Modern common rail engines usually specify to not add fuel the the on engine filter in order to assure all fuel is well filtered.

I am surprised that you cant find basic operation instructions on line for your engine. Look at the JD web site.
