possible automotive 340lph fuel pump problem help

Nissan370

Drive home from work today my car stalled in the middle of traffic
pulled off the road and looked under the hood try ed to start the car no fuel pressure
noticed the fuse for my fuel pump was totally burnt up.
so just to get home I bypassed the fuse car started up drove home

I checked the wires from the battery to the ppump it's a short run
my wires were upgraded when I went from a walbro 255 to a automotive 340.

never noticed a problem before car ran fine. Why would the pump pull
That many amps. Could the pump be going bad ?

Also now my fuel level indicator stopped working full tank it shows
no bars.
