Another turbo on N/A question sorry

[Peterr]

I didn’t fit anything extra,
Just removed the Bosch from a working engine and put it in place of the Lucas.

I have no idea what HBA is nor how to recognize it. Different from LDA?

Oh, we're both not English!
And you probably use Google Translate too.
Almost all Bosch VE fuel pumps for Ford Transit models use a hydraulic fuel corrector, also known as a particulate corrector. Its purpose is to limit fuel delivery per cycle as engine speed increases. There is one Bosch VE fuel pump model with a turbo corrector. Its part number is 0460414154. As boost pressure increases, the turbo corrector increases fuel delivery per cycle. An engine with this pump produces 100 hp.
I have such a pump—it was given to me as a gift. I don't remember who gave it to me—it was over 10 years ago, and now almost all Ford Transit forums in the former Soviet Union have ceased to exist. Someone from one of the forums. I was a very active participant. But politics has divided everyone. But that's the thing...
I used a pump with a turbo corrector for a while, but then I returned to using a regular pump with a hydraulic corrector. If you tighten the adjusting screw in the corrector cap, the fuel delivery at low RPMs increases and the engine's thrust at low RPMs increases, making driving easy and enjoyable—just press the gas pedal and the car picks up speed quickly.
With a turbo corrector, you need to maintain high RPMs—then the engine develops sufficient power and thrust.
Externally, a pump with an LDA has a thin tube running from the bottom of the pump housing into the "mushroom," while a pump with a HBA has a nipple in the mushroom cap for supplying pressure from the engine's intake manifold.
I've seen several articles online about converting an LDA pump to a HBA, but personally, I wouldn't do it.

Thanks for the explanation! Learning a lot here and enjoying working on my MK5 though frustrating at times. I had a look at another pump I have:

460 414 145 /686-2

This has that pipe from bottom to top. Is that the LDA?

Could this be a better pump for my turbo engine?
