magnum cam extension from hughes?

Looks exactly like the edelbrock pump I have for my carbed 360 magnum (I use the stock timing cover and modified the serpentine setup to drive only the Ram alternator and water pump). You can hear it when ignition is on, but it's not too bad (I can't compare, haven't heard any other electric fuel pump). With the engine running, can't hear it at all. I like the fact that you don't need a regulator.
