Check Engine Light Advice

I recently got a check engine light with the code p2067 on my 2005 Ford Freestyle and am a bit stumped on how to precede. Should I replace the fuel pump as a whole? or would there be better ways of going about this? My actual instrument cluster panel isn't being abnormal either. The fuel gauge does seem to be going down faster than usual considering I had just gassed up. Also the car starts up fine and hasn't died or stalled on me since this check engine light. I only ask because I have a trip back home from college and don't want to end up stalling on my way home and a mechanic isn't really an option because of the cost

Any advice on what things I should check to diagnose my problem helps.
