Did you try to put it in without the spring?
Did you take it all the way out and inspect it.
If it has a spring on it, then is the unit meant to move with pressure.
Maybe it does not have to seat?
Is a sleeve missing?
Or is the spring made to keep the bolt taught while under vibration?
Thus it is not meant to move.
Could threads be stripped and thus the bolt is loose?
Upon inspection of the holes in the bolt do they actually activate a catch
I try to give you my approach to solving this riddle.

I dont know anyone can help me. I am working on a Chinese made
Tractor King 404 tractor and cannot seem to get a bolt to go into
place. There is a tube coming off the fuel filter that goes into the
bottom of this assembly. The bolt on top was unscrewed and will not
go back in. It has a spring on it and when you try to push it down it
is hitting on something. there are some small holes in the top of the
bolt. I tried to push a small nail in there (thought it may release a
catch), but it did not help. However, I might not have been able to
push it in far enough to release the catch, if that is in fact what I
need to do. I posted some pics of what i am working with. If I can
get this bolt into place, I will be able to try and fire this piece of
junk up. I would appreciate any help that anyone can be provide.
