Hello gentlemen,
I would need further advice from you. Unfortunately, the previous owner removed the mechanical fuel pump and installed a 6V electric one. I have ordered a rebuilt pump from Max Merritt Auto. However, the original wiring is damaged . I'm not exactly sure how to connect everything properly. I believe I have it right based on the pictures, but could you confirm or correct me, please? I don't know what the MAN terminal is used for. I also don't know what the two terminals on the wiper motor are used for Once again, I don't know what this hose is used for. Is it connected to the inlet or outlet of the pump? As I mentioned before, the original pipes have been cut, so I have no reference to guide me Thank you for any advice.

Thank you for your honest response, and I apologize for my poor English, which may have caused some misunderstandings.
In the picture "2," there is a question mark next to the tube where it says MAN. Thanks to you, I now know what it means MANIFOLD and the hose is directed here. (My intention is to completely get rid of the electric pump and only carry it as a backup in case of emergency).

Thank you very much for the detailed description. I have looked at several photos and drawings, but they are not clear enough for me. Your description explains a lot, and if there were any photographs as well, it would be perfect. Unfortunately, no threaded pipes or fittings have been preserved; everything is cuted I will have to replace everything. Just to clarify, my fuel pump is labeled as follows M2049S.
The brake booster is not installed. Nevertheless, I'm glad that at least nothing is missing from the wiper motor. The windshield washers are also not part of the equipment, so both tube are bare. Thank you once again for your help. If anyone has any photos of the connections, I would be very grateful. After all, it is better for me to understand what I see rather than what I read in a different language.

My apologies too. I didn't enlarge the photos enough to read the MAN and WIPER labels. MAN would be the same as OUT on other brand pumps and WIPER would be IN.

I have never seen a 1951-1954 pump like that! The labels are not on any of mine and the arm is quite different but maybe a later or even more modern replacement. Even the screws are different. For reference of how the arm typically looks, here is the one I recently rebuilt for my 1951 although I didn’t take any detailed photos but I know it is not labeled as yours is.
On the fuel outlet, you will need a brass adapter from the 1/8” NPT (National Pipe Thread) to the flair fitting of the steel line and if you don’t have it and don’t want to bend the line yourself, Classic Tube has replacements in both steel and stainless. I would also advise getting a stock glass-bowl filter and attach it to the carburetor, then connect the line to that even if you already have a non-stock inline filter somewhere. It will not only look proper but it will also let you see the fuel flow. For the vacuum booster hoses, one connects to the wipers and the other connects to the intake manifold through steel tubes but your manifold fitting may have been plugged when the old pump was removed. I believe the steel line connected directly to it using another adapter, then went behind the manifold to the pump where it connected by way of a short piece of rubber hose. There was a bracket that held them in place. Again Classic Tube has these tubes pre-made but you’ll have to get the bracket through one of the dealers.

Yes, you're right. That pump is indeed different. As I later found out, this pump is only for the 1953 Clipper model, while other models, including the 1953 model, have a pump like yours. I have no idea why, but it seems to be the case.
Thank you for the good advice and tips. I will first have to determine the actual condition of the pipes, and then I will decide. Ordering pre-made ones would certainly make my work easier, but considering the shipping costs to Europe and various taxes, it doesn't make financial sense for me.

Even my former all original 1953 Clipper Deluxe had the type I showed!

Interesting, for example, Max Merritt has it divided like that.
