Is the Bosch 044 pump enough to run 1000rwhp?

No, especially not with FI.

So the dual pump setup is my only option?

You could do dual pumps, or a big single pump, such as a Magnafuel.

I would say that dual pumps with one referenced to MAP via hobbs switch would be the best bet. Thats what Ive done in the past at least.

Why a bigger return? You are flowing less fuel back to the tank that makes no sense besides the fact that all fuel kits have a smaller return too.

Probably a typo error

I know most of the truck guys just unbolt and slide back the bed to do fuel system upgrades. How much harder is it going to be to upgrade the pump on an Avalanche?

No, in two posts he put the feed as being smaller than the return. I believe he posted the same setup in his build thread. Just wondering why he believes the return should be larger.

The cheapest setup for you is going ot be an 044 in the tank, professional products rails, edelbrock FPR(cheapest thats still good quality), and -6 return line, drill your fuel bucket for the return and enjoy 800rwhp. I think a lot of guys in this thread are overthinking things. If youre going for 1000rwhp then youll need more but Id bet and 044 intake and 044 inline could get you 1000 to the ground. I plan on running that setup when I switch to E85 and a turbo. Remember Parish ran over 1000rwhp with stock lines(03 return setup) and twin 255s off a hobbs switch. Simple, effective and no where near as expensive as some of the setups you guys are running.
