Re: [DML] Noise from fuel pump

[Warren Wallingford <warren@xxxxxxxxxx>]

I killed a Bosch pump in the desert once by putting cold gasoline on it. 
  I know an owner who did the same in Las Vegas.  Be careful, the pump 
is weak and will quit directly.  Give me a call, we'll replace it with 
proper documentation.  It will act better when the weather cools, but 
should not be relied on.
