What is this?

Why is there no brake booster here. What are the hoses for?

This is on Craigslist as a 1979 F350

It's a hydroboost- runs off power steering pressure instead of a vacuum diaphragm.

They're especially advantageous where available space dictates a small vacuum booster. Not sure if it has a big advantage over a stock 350 booster (which is really large in these trucks) or not.
But it sure opens up some space in there.

I don't like the extra plumbing, but can't argue with their power.

would guess it's also good for a high perf engine that doesn't make a lot of vacuum.

Never knew the dendsides had a hydro boost option. I guess it was a one ton only option?

I don't believe there was. This would have to be a PO retrofit I think.
Of course, I've been surprised before, and Ford does use hydroboost on some stuff. And it's been around that long too. Saw one of my first on an '80 K30 GMC truck.
But I've never seen one on our vintage Fords.

Sure sign the truck was originally equipped with the Olds 350 diesel.
