I forgot the general rule but I think it's like 1.25x fuel increase with series and 2x fuel increase with parallel.. I assume you already know you need at least 1600cc injectors? You might also want to run your second fuel pump off of a pressure switch and relay..
I've never seen or heard of anyone using the charcoal canister line as a fuel return.. Interesting setup.. You should be able to flow enough using the 2 hard lines as a feed..

Thanks! I've actually got confirmation from a local tuner that he had actually done this same configuration and made up to 750whp. Basicly ran it just like you said the 2nd pump on pressure switch which activates when boost pressure hit 10psi. So this confirms my setup and will be retaining it.

Supra guys run this same setup with twin walbro's and put down 8-900 wheel all the time.

I'm trying to keep the setup as simple and without too much compromise. dual dedicated 6an feeds is plenty for my power goals. Thanks for the input!
