The stock fuel pump will not be enough, you will at least need an inline fuel pump like the one that drag uses with their kits. Or, you can get the walbro 255 intank fuel pump. Send me an email if you need an inline pump, i have one.

He is going to run bigger injectors, so he wont be pushing high pressure, no need for an inline pump
I ran RC 500cc injectors w/ hondata on my stock pump and made pretty damn good power (and was boosting a little over 10 psi). We've also done a couple SAFC hacks at 7 psi on stock fuel pumps. If you are gonna stay around 6-7 psi, your Stock Fuel pump will be just fine.

Re: Do you need a fuel pump with AFC hack? (Mase)
I agree with you mase. But you think that 6 psi is about max for a stock pump? Just wondering if i am going to need an aftermarket intank. I plan on about 8 daily.
thanks

its really up to you!
you dont need the pump to run the hac it will work fine! im at about 7-8 psi on the hack wiht stock pump......... but if you want the piece of mind knowing that you have the better pump go with it! but it isnt a must have, unless your putting out a lot of power and boost!

I can only say from my experience. My stock CRX pump was not up to the task of of even 49psi fuel pressure (42 static + 7psi boost) while using 450's. Swapped in a GS-R pump and everything was ok. I did the calcs awhile ago, but stock Civic/CRX pumps (non-DOHC) can not match the rated flow of 450cc/min injectors.

You should get a 255, look into the Walbro 255. Lightningmotorsports.com has super good deals on them right now and they do good business.

Re: Do you need a fuel pump with AFC hack? (b18onboost)
it's usually
high flow (ie bigger injectors) <--> high FLOW fuel pump
high pressure (fmu) <--> inline fuel pump (which is high pressure)
high flow (ie bigger injectors) <--> high FLOW fuel pump
high pressure (fmu) <--> inline fuel pump (which is high pressure)
