A Holley Blue fuel Pump?
Mallory?
Weldon ?
Walbro?
"T" - Rex pump ?
Fuel pressure test with a gauge will help troubleshooting.
If You have an external WELDON EFI- CARBURATED Fuel pump,
You have the very best $$ money can buy.

I wouldn't worry that much about the noise. If the pump is contacting the frame, it could make a racket. As Brian suggested, check the pressure. If it is putting out 13-15 psi and maintaining the pressure, you should be ok. Maybe some rubber insulation between the pump and frame is all you need.

Wait, you have an external pump so the 85 won't work, thats for inside the tank. Are you using the crossfire regulator or something else?

Its likely a Holley brand electric external fuel pump.
A Red Holley Fuel Pump OR a Blue Holley Fuel Pump.
Both models are somewhat noisy in operation.
Normal noise from them.
As long as either model pump does not quit spinning & delivering fuel,
You are OK.
