Electric Fuel Pump Cut-off Switch

[Roland Dudley <cobra@cdc.hp.com>]

I'm planning on replacing the snake's mechanical fuel pump with an
electric pump and I've got a question about the pump arrangement on
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?
