Finally got my hands on a 2.25 diesel engine in good shape and even better a great price. Only issue is a cracked exhaust manifold. I managed to locate one on the web and it should arrive tomorrow.
Does anyone know how power assist brakes work on a diesel. They don't have the usual setup for vacuum that a gas engine has so how what or where would the brake booster be connected to?

What is the diesel going in? Year, model, etc.
Btw, I am JEALOUS!!! I've recently fallen in love with diesels.

In theory it is a 1965 SIIa with a gas engine but due to a little sleight of hand by the prervious owner it was registered as a 1971. It is a bit of a mixed bag but the body is clearly an SIIa. The body and drivetrain look like they were on a military style frame and the engine serial number suggest it really was a 1965.
It has a new frame and I recently sourced a SIII 2.25 diesel for it. I am working to get the axles rebuilt so I can have a rolling chassis and then I will rebuild the bulkhead. WIth any luck I will get the engine in place sometime late January. From there I have all the misc fittings to clean up and paint before installation.
A huge amount of work to do and I really want to make sure that I rebuild or refurbish the critical running gear to prevent problems later on. I am hopeful it can go for a road safety sometime this summer.
I will post a picture or two as I make progress.

I've never had my hands on a 2.25 Diesel but on the 2.5NA there is a vacuum pump where the distributor would be on a petrol engine that supplies the vacuum to the break assist.

Sounds to me like a good reason to check out the manuals. Mine has the petrol so I doubt sending you a photo would be of any real help.

The engine is likely out of a SIII so I don't have a manual for it.
I took a close look and I very much doubt that there is a vacuum connection!
Back to my original brake plan!

The later diesels had a vacuum pump as was previously posted.Land Rover had a kit for the earlier diesels like yours,but it's no longer available.It basically was an extension housing for the inlet manifold with a throttle plate,a linkage rod,(connected to the throttle bellcrank),and a ported vacuum fitting that connected the hose to the brake booster.The intent was to reduce the vacuum to useable levels so the booster wouldn't be damaged.Your engine has high vacuum due to the 23:1 compression ratio.
