I would recommend against trying to put your pressurizer inside your fuel
tank like that. Better to have it in a separate cylinder with a
valve/regulator to the top of the fuel tank so it can be adjusted and
worked on separately.
On basic rocket plumbing, older materials are still good and easy to
understand. I like How to Design, Build and Test Small Liquid-Fuel Rocket
Engines, by Rocketlab. A few scanned copies are floating around the
internet.

New to the forum. Forgive me if this is not how things work.
My general questions are:
How can one make or obtain a tank for propellant when you want to use
inert gas to pressurize it. Should I purchase a bladder and try to jam it
into an old chemistry cylinder? Or should I have the thing professionally
made (for like $2500 a piece). The rocket size is about 5 inches in
diameter with a design thrust of around 2000 lb. Kerosene and LOX
How should I meter the flow? Should I use an orifice or venturi? How can I
insert the pressure gauges and thermocouples everywhere? How do the
pressure gauges work?
Any help would be greatly appreciated?.
