Tanksinc in tank fuel pumps

I have the tank, their pump, sending unit, and "corvette" filter/regulator. I have about 400 miles on it with a customer port injection setup. Everything works great so far. The pump can be hear for the 3 seconds it runs when you turn the key, but once the engine is running it can't be heard.
The level sensor did get stuck down when I first filled the car up and I was pissed I would have to drop the tank to get to it, but after an initial test drive, it freed up and now it works fine.
U just described my ext. inline pump , after the car starts , cant hear it . No problems tho-----
