Would this be possible in a Rocket Engine combustion chamber

Lets say if i have a bell nozzle rocket engine such as this one : http://www.braeunig.us/space/pics/fig1-04.gif and inside the combustion chamber i have an average pressure of around 300 psi. If i wanted to feed in liquid fuel into it while the fuel pump is only able to supply 100 psi of fuel.

my question is would this be able to work? or will it not be able to send any fuel inside the rocket engine.


Thanks

The performance specs of the F-1 rocket engines used in the first stage of the Saturn V rockets which sent the Apollo spacecraft to the moon are pretty impressive:

For liquid fuel based rocket engines, the the fuel pump into the rocket engine has to have a bit greater pressure than the pressure in the combustion chamber in order for the fuel to flow into the combustion chamber. There are various ways to achieve this. Links to articles:

That is pretty impressive given the fact that chamber pressure was around 1000 psi
