[DML] Re: Water in gas?!?

["dmcchaser" <dmcchaser@xxxxxxxx>]

  I don't have a lot of experience with water in the fuel on our 
Deloreans, however I am familiar with the K-Jetronic system on other 
vehicles.  So my two cents may be a little off.

  First off I don't think you need to worry about blowing a head 
gasket during the backfire, possibly damaging/bending the fuel 
metering flap or blowing out a weak muffler but the head gaskets 
should be fine.

  From past experience I know that the fuel distributor can be very 
picky about any water of debris in the fuel supply.  The fuel 
distributor itself is non-servicable but if you were to take it apart 
the fuel metering piston (the correct name escapes me) will not fit 
back into its bore with fingerprints on it.  Not dirt, just oils from 
fingerprints.  So you see the tolerances are very fine and the fuel 
supply must be clean.
  If you have enough water in your fuel that it is coming out of the 
injectors cloudy I would recommend draining the fuel tank completely 
and starting with fresh fuel.  Also change your fuel filter.  I know 
it's a hassle, but it's better than having to replace your fuel 
distributor.
