I'm looking in to retrofit a OM617 into something that does not use the typical vacuum assisted brakes. I'd still like to use vacuum to shut off the car so I don't want to eliminate the pump. I'm not sure what the best way to go about putting a system together so I can still use a electronic valve to open and shut off the engine.

I'm not sure if I should run a filter on the end of the hose coming off the vacuum pump, or run it to some kind of a canister reservoir to hold vacuum.. But I'm not sure how the pump operates... would it stress it if I plumbed the pump to a closed reservoir and used it for holding enough vacuum to shut the car off. Would this cause it to pull too much vacuum and collaspe the hoses, or does the vacuum pump have way to "releif itsself" once a certain vacuum measurement is reached?
