Hudson electric fuel pump

This was in a box of Hudson bits and pieces that was given to me recently. I'm told it was a trunk/boot mounted option in the 30s and 40s in place of the mechanical fuel pump. It was aimed at those who used their cars at high altitude and/or used them infrequently in cold areas.

I believe that was called an "Autopulse".

Thanks for that Jon, googling autopulse turns up photos and more info.
