It may be a leak. Maybe a loose clamp or something.

Edit: If you don't find any leaks then you can swap pumps with a friend if possible to verify that yours is actually bad.

If u have a fuel pressure guage, check that the pressure stays constant while accelerating moderately or WOT. IF it spikes back or falls ur pump is bad. It should stay up there until you take ur foot off the accelerator.
