Why does the oil not rise whenever I pump?

I prepared this stove I washed all the parts When it is blown into the tank from the air hole by the air mouth, the oil rises up from the Ziggler But no matter what I pump, it is useless Please advise how to repair the pump, thank you

 

This is the photo of the defective stove

 

Is the leather pump cup dry or damaged?

Is the PIP in the NRV stuck and not allowing the air to enter the tank?

 

The piston of the pump is healthy and the leather of the pump is also good. The end of the pump is blocked

 

The leather of the pump seems to be healthy, but the end valve has a problem

 

I made a wrench to open the pump nut, but it did not open

 

Spray some WD40 or similar release fluid down the pump tube and leave it to soak overnight. Replace the pump and try pumping it up. Get some air pressure under the pump and give it a good hard rap with the palm of your hand.
I have released a few like this.

 

سلام ممنون از کمکتون بله حتما تستش میکنم

Hello, thank you for your help. Yes, I will definitely test it.

 

Be careful that you do not break the solder joint of the pump tube.
These are old stoves, not firewood.

 

Just remember that WD40 is a water displacement product and not a penetrating oil.

 

Hello, I don't understand what you mean

 

Agreed.

If you cannot get Kano Kroil....
Mix acetone and ATF (Automatic Transmission Fluid) 50/50 (equal parts)

Penetrating oil soaks into tight/hardened spots and helps lubricate and makes removal easier.

WD40 displaces water.

Hello friends, thank you I used a type of acid that was used to open the hole in the radiator of the heating package The way for air to enter and oil to exit was opened The acid caused the pump to be repaired, but it spreads out from the valve and valve of the oil
In short, we had fun with Primus for a few hours, thank you

You are missing the flame spreader.

Hello, yes, unfortunately

 

Hello, dear friend, I have a question. What is the maximum allowed amount of oil that can be poured into the Primus tank? I poured oil in this oven up to the top of the pump, but the fuel did not return. Should the amount of oil be up to the top of the pump or not? Thanks for the advice

I mean, if I pour a little oil, the fuel will not return
