How does the MiG-29 fuel system work? Like, where does it store around 300 cubic feet of fuel?

Also, which fuel does it use? Is JP4 preferable?

    $\begingroup$ I'll comment on the "also" question, as it's not worth an answer. MiG-29, like most Russian/Soviet jets, normally uses the TS-1 kerosene. It's closest common analog is Jet-A1, but like anything in aviation, every type of fuel has to be specifically approved. Jet-A1 and JP-8 are approved, AFAIK. I'm not sure about JP-4, but it's certainly not 'preferable'. In practice though, a jet engine will burn almost anything, and in times of war you can even use diesel fuel. $\endgroup$

The aircraft is equipped with seven (7) integral fuel tanks: five (5) Center body fuel tanks and two (2) wing tanks. Center body fuel tank #2 serves an an engine feeder tank with all other tanks transferring fuel to it via a network of fuel pumps for consistent weight and balance. The aircraft can be refueled by means of a single pressure refueling receptacle located in the port main landing gear well.

Like every plane, the MiG-29 stores its fuel in fuel tanks ;)

On a more serious manner:

Generally speaking, there are 6 internal fuel tanks: 4 distributed around the fuselage and 1 in each wing.

Later versions (namely the SMT) have larger internal fuel capacity thanks to the enlarged spine.

The exact locations of these tanks can be seen in this cutaway (src): 63, 72, 93, 107, 187.

In addition to these, the 29 can also carry 3 (1 in the very early versions) jettisonable external fuel tanks.

    $\begingroup$ you should also mention external fuel tanks (that can be jettisoned). $\endgroup$
