Sailing Dream
This is just my opinion. We will see of others differ. I would still fill the tank after I added fuel. If you don't add fuel you run the risk and probability of condensation. Unless you feel you might want to empty the tank in the spring and then clean it. Definitely a good idea.
As for the starting issue. 20 seconds on the glow plugs in the summer is not abnormal in my experience.
Search this site for a solenoid project regarding the glow plugs. Another well worth it upgrade. If it is not already done.
