[V8] Fuel Pump Failure Modes

[quattro + 5 or 8 = fun]

steve-

i certainly have had the pump come back to life.  on my old 4ksq, when i
drove it daily, i was to poor to afford a new pump when they went out.  SO,
i had "pull n save" pumps in my trunk along with the tools to replace the
pump AND, most importantly my pump cpr kit.  that consisted of a hammer and
a block of wood.  I would put the wood on the pump and beat it with a
hammer.  I could usually get 5-10 cpr restarts before it would fail forever.
I am glad i now have a job that pays well and newer cars (although not that
much newer).  I still have the 4ksq.
