Fuel pump tapping

Tonight the starter circuit went bad left me stranded until I jumped the starter to get going. Then on the way to the gym she developed this loud tapping noise in the rear. If I hold my ears closed she drives fine just like any other day. Am I right to think the fuel pump is the only thing back there to make the noise? I ruled out the vert pump.

I won't have time to check her I UT in the next few days. Looking to get a jump on parts if needed.

Maybe the pump is just loose. IIRC the pump is external?

Thanks in advance!
