How many PSI does the fuel pump pump fuel to?

I want to try building a homemade jet engine and I was wondering how high of pressure the CB7 fuel pump runs at. If it's high enough I can use it to pump fuel for the jet. Thanks!

OEM fuel pump is around 30PSI.

OEM fuel pump is around 30PSI.

The regulator on the fuel rail bleeds off pressure that exceeds 30, but I'm guessing the pump itself is able to push harder than that. With an external pressure regulator, I don't see why you wouldn't be able to get at least 40. how much pressure do you need?

p.s... ever see http://www.colinfurze.com/ ? dude does a lot of crazy stuff with homemade jet engines.

30 psi should be plenty! Thanks, dudes!

I read the title and immediately thought

How much fuel could a fuel pump pump if a fuel pump could pump fuel.

so appropriate for the thread, thanks for the laugh!

If you completely block the return line from the pressure regulator, the pressure goes to about 60 psi.

Do a little math and you could interpolate the pump curve. Remember, higher pressure is lower flow rate.
