Is a fuel pump required...
 

...for use with a FMU at only 5 PSI? I have 450's but not s-afc yet, and I'm ready to go boost. Would a 10:1 FMU be sufficient for a few months without a fuel pump?

ive heard you dont need one for that amount of boost, but i use one...also, i hope youre not planning on using the 450s without the afc

No I don't have enough money for the afc yet. And logically i can't use the injectors without the afc. But what I do have is a FMU. I'm just curious if the FMU will keep me rich enough without a fuel pump at 5 psi.
