Evan, something like
this?My truck is still 6v, but I do run a 6v to 12v, 10 amp convertor. Wonder if it'd supply the pump above? More research to do.

That's a generic Dorman 904-214. I contacted Dorman for the specs relating to whether it had a self contained shutoff switch. This is the reply: "The pump will shut off at 15" of vacuum, the pump operates to maintain 12-15".
