[V8] Fuel Pump Longivity?

[Bill Hitzler]

The fuel pump failure thread got me  wondering; what's the longest a
fuel pump has lasted in one our V8's? My 1990 has 165,000 on the
original pump. I'm hoping that posting this thread doesn't jinx my pump,
it's been working flawlessly. A couple of years ago another lister
brought up how he used Marvel Mystery Oil in his gas tank. About 4
ounces per 20 gallons of gas does make the fuel pump run more quietly.
I was considering swapping in a new pump this summer as a preventative
measure but now I'm curious about others experiences with this. Thanks,
William
