Narrative:

A center fuel boost pump failed to pressurize leading us to the QRH and appropriate checklist. Upon executing the checklist we noticed the wording to be in our opinion confusing and inaccurate. On QRH page reads'crossfeed switched...on' and 'crossfeed switches...off'. The terminology 'on' and 'off' in this context is wrong. Although the switch may be deemed on or off by an electrical engineer; we are manipulating a valve which is either open or closed; not on or off. The present terminology is confusing and should be changed to the more accurate and descriptive 'open' or 'closed'.

Title: After a B757 fuel boost pump failed the crew referenced the QRH which describes the Crossfeed Valve as ON or OFF when a proper description would be OPEN or CLOSED.
