Nitrous on a 340 100 shot

Was shooting the **** with a friend that runs a bunch of NE stuff. They usually want around 8 psi, so your fuel pump isn't going to cut it from the suppliers perspective.
Thanks! Yeah I read that in the instructions after I downloaded them on your advice. So I'll get a pump that can go to 10psi as that's what the 250 shot requires and the 100 does need 8. I'll also get a fuel pressure switch to run in an sttempt to safety the system somewhat.
