Well im doing my log book but I fuel and stayed at a truck stop for about four hours before started driving. Can I legally put when I started driving and leave my fuel off duty and out of my 14hr log.

Answer - Lifeasatrucker:

No. When you move the truck to fuel, it will be considered on duty not driving flagged as fueling. (Note the location information)

It uses a minimum of 15mins of your 14hrs.
