I need to remove a brass manifold from a steel air tank. Have been unable
to budge it using Kroil and heat. Looked in archives but didn't find an
answer. Please help!

I bet its knurled and/or soldered in place. More heat, more force.
If its threaded, you'll still need more heat and force!

if it is a pipe thread , have you tried tightening it a little before
attempting to loosen?

old pipe fitters trick

I don't know if it will help, but ammonia refrigeration systems use steel
and brass is specifically not permitted due to severe corrosion. Ammonia
might dissolve the brass enough to loosen it.

Good Idea, but it won't float. The ammonia will
dissolve the zinc out of the brass and just leave
a brittle mess. Any pressure will break it.

From the description and header I assumed that was the idea, to get rid of
the brass part.
