[V8] hissing sound from the fuel pump?

[MORRALEE David]

 Some of these pumps can be a bit noisy in these cars. But I would be
changing out the fuel filter first as it's quick, easy and very
inexpensive to do .

The few V8 tanks i've pulled aren't coated and rust very quickly. If the
car has sat for any length of time with low fuel it's possible that the
tank top has rusted and it's flaked off and collected in the fuel pump
basin.

Another thing is that the internal rubber return hose has disentigrated,
or the fuel pump is just old and used up.
