[DeTomaso] Engine stalls on start up -Help!!!

Just as a note, SCCA tech requires that the fuel filter be installed before the fuel pump, so that if it ruptures it is not spewing fuel from a pressurized fuel line. Our fuel lines are now built to these standards using Stainless Steel Braided PTFE (Teflon) fuel lines for today's pump gas and metal encased AN fitting Fuel Filters. Barb fitting and Clear Fuel Filters are not recommended, especially on a pressurized fuel line.

       If I were you I would install the fuel filter now, before you suck up
       some more debris from the tank and it plugs up the jets more. Install
       it low in the fuel line, not up by the dizzy. A leak by the dizzy can
       start a fire
    
       I have never heard of a car being run without a fuel filter.

         Folks,
         Thanks again for all your feedback!    I called Demon, the carb does
         not have an inboard filter.  I am going to spray Gumont carb cleaner
         and see any improvement.  May have wife or friend watch inline fuel
         pressure gauge.  (I understand 5-7 lbs is good)?  After that I'm
         going to trouble shoot gas delivery if needed.  Also going to add an
         inline fuel filter.
         Whats this about  the mesh sock in tank pickup?  How can i see if
       mine
         degraded and broke apart?
         Thanks everyone!!
