I filled up today and I inserted the nozzle as far as I could get it. I held the nozzle and fed the fuel in slowly. It filled all the way up. Maybe I wasn't getting the nozzle passed the second check valve. I have been filling up at service station quick marts. My ford that I had previous to this Ram filled better with the nozzle not stuck in as far.
Thanks for all the suggestions.
