So I know this sound pretty dumb, but is running the fuel pump continuously for a week or so a problem?

My circuit-opening relay's on the fritz. I already ordered a new one, but I'd still like to drive the van around while I wait. Am I begging for catastrophic failure if I just jump the relay and run the pump continuously while driving? Casual in-town driving vs long highway drives?

Doesn't the pump pretty much run constantly anyway and the fuel just goes back out the return line?
