[V8] Does a T44 Fuel pump TSB apply to V8?

[urq]

I'd recommend that you not assume that the hissing noise is the fuel pump
... from the sounds of the issues you've had with mixture you could very
well have plugged cats or an exhaust leak.  A quick listen under the car
should help resolve the issue ... the fuel pump is in the tank, so the
hissing would come from the back of the car.  The exhaust hissing should be
coming from the header / cross over / cat inlet area at the back of the
engine.  

I've had the fuel pump go on both the '91s now ... don't recall either pump
getting excessively noisy before failing.  One died in a parking lot without
obvious warning signs, the car just wouldn't start after stopping for an
errand ... the other died while the car was in motion ... here again with no
apparent warning signs.  If you know your car still has the original fuel
pump you don't need to consider whether or not the coating is coming of the
inside of the tank ... the pump can go at any time due to old age ...

   I found this searching today, and was curious if this applies to
our V8 fuel system?
 If noticed mention of "Lint' of sorts on some fuel pump screens, seen
a bit about fuel pump failures,
but am still drawing little in the ways of conclusions and what to
look for when failure occurs.

I've been informed earlier that my loud hissing/buzzing sound is
actually my Fuel pump, here I thought it was
an Exhaust leak.
