Hope you can find your way through to a solution. Don't give up!!

This is a pretty easily solvable problem really. There are LOTS of electric vacuum pump options out there. We can work on this for you and find you a part number to order if that is what will help.

Almost every modern turbo gasoline car has an electric vacuum pump to help with brake assist. I have seen them on Volvos, Saabs, Audis, Volkswagens, Subarus.... I am sure there are more.

In fact I have a Subaru one sitting on my workbench right now. I would be happy to donate it to you if shipping to Italy can be arranged.

The whole process is not complicated. Add the vacuum pump and wire it to run whenever the key is on. Then just remove the vacuum pump pushrod and install the vacuum pump without it. You can also make a blockoff plate but just having the pump sit there dead works equally well, whatever you find to be easier.

Thank you V8
This message warms my heart …
It would be a tremendous help to tell me what set up i should buy !

Here is an example similar to the part I have seen off a Subaru. The one I got came with a VW Jetta TDI that had a failed mechanical vacuum pump and this electric pump was powering the brakes. It worked great!

This one is $49 on ebay. I am sure similar pumps exist on ebay in France. (Sorry, I said Italy before, for some reason I had that in my mind as your location. Apologies!)

All you have to do is wire it to a sufficient power source that runs whenever the key is on. If it were me, I would probably build a simple circuit using a 4-pole Bosch-type 30A relay with inline fuse direct from the battery, with the relay energized by a wire tapped off the injection pump solenoid which is hot whenever the engine is running. You don't want to overload that circuit to actually power the pump -- hence the use of a relay.

Thank you very much
If I understand correctly, any 12v vacuum pump would
Work without any pb?!

[v8volvo]

Correct!

Any 12V pump that is designed for continuous operation.

If it were me I would probably add a vacuum reservoir as well. If you do that, then the pump can be sized smaller since recovery time will not matter as much.

Ok I see !

I will probably do the job the most simple way
I see I have two option
1) the most simple : buy a kit all included , but it s not cheap: about 200€

2) take a random stock pump from a car ,remove the connector
And wire it the following way : first to the inline fuse, then to a relay , and then
The relay should be wired to a pressostat so it can stop working when the vacuum reservoir of the pump is full. It will cost me way cheaper, but also requires a lot more work to prepare the electrics.

So I just bought this one !
