     Presuming your tank runs dry just about the time the engine completely
     fills up,(Don't count on your rings to keep it topside), including 
     your oil pan, etc. Anyone ever see a "top-fueler" blow an engine at
     the end of a run? (One of the safety features of a dry-sump oiler is
     when the engine blows, you're not adding x-quarts of flaming oil to
     the mix.)
     
     Not to mention the possibility of accidential ignition via water 
     heater, frig. furnace!! or other spark.

These inertial and oil pressure-regulated fuel pump cut offs have an extra 
connection on them so that you do indeed get fuel pressure when you turn the 
key to "start". They are absolutely essential. Think about it...What would 
happen if you had a short and your fuel pump continued to run, 
overnight-say. It could pump a full tank of gas into your engine. (don't bet 
your life on a carb. float valve) When you come out in the morning to start 
the car the cylinders are full of gas and when you try to turn over the 
engine into a hydraulic situation you break something-EXPENSIVE. (This is in 
addition to the problems with tip overs, etc.)

=>|     That's just what Tigers need:  ANOTHER reason for the fuel pump not 
to
=>|     work.
=>|
=>|     There's no stock cutoff.  I have considered installing an emergency 
=>|     cut off of this type.  Lots of Fuel Injected cars have them, which 
you
=>|     could grab at a "strip it yourself" parts yard.  I seem to remember 
=>|     something about a cutoff on my wife's Sable wagon, located behind a 
=>|     little door on the passenger side of the "wayback".
=>|
=>|     My Mom's Vega had an oil pressure cutoff for the electric pump. You 
=>|     need oil pressure before the pump turns on, unless you install an 
=>|     extra pushbutton switch to bypass the cutoff.  Also, there might be 
=>|     circumstances where you would rather risk trashing the bearings than 
     
=>|     come to a halt right there (approaching train, etc.), and this
=>|     decision would be out of your hands.  You will find these switches 
in
=>|     racer catalogs.

=>|I'm planning on replacing the snake's mechanical fuel pump with an

=>|Tigers.  My son's TR8 has an inertia switch which cuts off power to the 
=>|fuel pump upon heavy impact.  I've also heard about switches that cut off 
     
=>|pump power when oil pressure goes to zero.  Did Tigers come with any sort 
     
=>|of emergency cut-off switch?  If not, have any of you installed one?
