Edin Dzeko's wonderful double and Frank Lampard's fourth goal in three games sealed a 4-2 victory for City
Hull live updates
The Football Association has confirmed its decision to reject Hull's name change is currently in arbitration.
A statement read: "The Football Association has agreed with Hull City to clarify the position regarding the club's name change application.
"On Wednesday 9 April 2014, The FA Council rejected Hull City's application to change its playing name to Hull Tigers.
"The club has chosen to commence an arbitration under Rule K of the Rules and Regulations of The Football Association to challenge the decision of The FA Council."
Debut goals from Hull pair Abel Hernandez and Mohamed Diame were only good enough for a draw against West Ham as a Curtis Davies own-goal ensured the spoils were shared in a breathless encounter at the KC Stadium.
The home side lost the lead twice, club record signing Hernandez getting the ball rolling with an impeccable first-half header and Diame restoring the advantage against the side he left on transfer deadline day.
In between Enner Valencia had marked his first league start with a blockbuster strike from 25 yards and the 2-2 draw was settled when Diafra Sakho's modest shot evaded Allan McGregor, only for Davies to bundle over his own line.
