...and just to make it tougher, something that could be used for continuous street use?
Looking for something for a street diesel with lots of boost

Hi Ross,
it doesn't sound like it, but maybe things have changed since this was written (and this is from a manufacturer, so maybe take it with a grain of salt). Good article with a good amount of info on different styles of vacuum pumps and their performance.

Not to my knowledge.
How about a pan evac setup? Let the headers/exhaust manifolds scavenge?

How about a 32v cobra brake booster vacuum pump?

I don't think the exhaust is efficient enough and at WOT there is back pressure with a cat and exhaust filter, of course that isn't good, but it's a fact of life
The truck only hits about 40 psi max, its not a racer, and I don't need to pull high vacuum numbers but many of them are fighting seal failure and with the siphon into the intake, it can oil up the intake and cause coking of the fuel heater overt time. So looking to see if there is something that would take the place of a good PCV
Guys just vent the valve cover to stop the coking, but I'd think there would be power and sealing benefits from coming up with some vacuum, plus it can make a mess under hood with just a breather too
I'll look at the Cobra pump, but my guess is that there isn't anything electric with enough volume for 6.7 liters at 40 psi
