In my 1984 Westy my fuel pump was screaming so I swaped it for a know good one(not option for every) and still sreamed. checked fuel pressure way to high, my pressure regulator took a shit and was letting the pump run at full speed all the time.
just my experiance with noisy pump. no problems with fuel pump since new regulator installed (last Oct.)
