A properly full overflow tank does not confirm a full heater coolant tank. Only opening the radiator cap and making sure the tank is completely full confirms that. Missing overflow hose clamp(s) and/or cracked overflow hose will let overflow tank stay full and coolant tank slowly go down.
The Least important part of burner service is the fuel filter, especially the big one on Newels. The most important part is the nozzle and then cleaning the combustion chamber. Replacing the filter and not the nozzle accomplishes nothing.
Once the new nozzle and clean combustion chamber is in place, run the burner once per month or more to keep it operating properly for 1, 2, maybe 3 years. That is every month year round, occupied, stored or sitting at some repair facility.
