+1. Want to know the car.

I've never dealt with vacuum shutoff. But on trucks with electronic cylenoid shutoff I ripped it off and put on a choke cable.

Is something like that possible? I'm in the dark here.

I am curious to know about vehicle too.

Even better, Ill minimize the complexity of the vacuum system and keep my vacuum pump healthy.

Range Rover Classic potentially, stay tuned my diesel loving friends. I've been gathering up my photo's along the way and will be comprising a build thread soon. I've been waiting on finding the right recipient for the engine. It's a toss up between the classic and the disco right now. I've got a manual transmission of choice along with a adapter plate already fabricated and ready to rock.

Here is some good info in this thread on the vacuum pump.
Not sure if the answer you are looking for.

He mentions that the pump doesn`t produce vacuum all the time, when it reaches the set point, she lays back till the need for more vacuum is needed, sort of what VSTECH mentioned.

VACUUM PUMP FAILURE! Are you neglecting yours??

Exactly what I was looking for Charlie, thank you.

Sounds like a cool project. What transmissions are you considering?

Neat stuff, looking forward to hearing about your conversion.

I went the electric pump route in mine, and if all I needed was to shut off the engine I would probably do the same with a much smaller cruise control or similar pump.

Mach4's testing with converting his diesel SL to an electric pump lead me to believe that the cars with an automatic transmission would ALWAYS have a vacuum leak.......and therefor the vacuum pump would be running constantly. I don't think many give those vacuum pumps as much credit as they deserve, many last longer than entire engines made by other companies.

Ahhh my fellow land rover friend. That would be the R380 land rover manual trans. Allows trouble free mounting for transmission, LT230 and drivelines to stay in their proper and stock locations. Here is a picture of my homemade adapter.

Infact, are you the guy who has a couple vids of his series on youtube? I made a comment on your video a few months back and you responded.

Appreciate man, been through your build a bunch. Almost went yota myself.

Nice work, btw i have some plumbing for the shut off i was going to put in before i decided to go manual. Nothing big, a couple of fittings and a push button with a tiny hole on the shut off side with would allow vacuum to drain so the valve is in the on position next time you try to start it.
Last time i remember seeing it my 4 year old was playing with it but i'm quite sure i can locate it eventually.
It's yours if you want it.

Appreciate it man, I think I've got it figured out though ... least in my head. I plan on using the overboost protection valve (closed when energized / open when no current). Just run 12v switched power to it inline between vac source and shutoff. Bingo. When I find out it doesn't work, I might come running back to you for that offer though!

Still debating on the Classic Range Rover or Disco, but it's gonna be Land Rover.

Sounds like it'll work, the only thing you will need power to keep the engine running if the fuse blows the engine will stop.
