First off, I'm a newb.
Second, I did search.

I know most people are happy with the Walbro 255, but I can't put all the numbers together to find out how much fuel I'll need pumping through 1000cc injectors at 8500 redline. Will this pump hold up and maintain pressure?

I'm thinking no. I really can't put the numbers together that is why I'm here.

I thought about an inline, but it wont help my intank pump any. Correct?

I'm thinking about the aeromotive A1000, but then comes the question on how to mount it on a stock fuel cell. It is gravity fed, so... I'm thinking this would be better with an after market fuel cell. I'm not sure I want to do that.

Aside from the pump, I'm figuring I will need to get bigger fuel lines.
Anyone know where a newb can find some understandable info on how much a fuel line can flow before becoming the restriction?

If I can't find any real info, I'll wait till I tune. When I start leaning out the plan would be to upgrade the pump first, then tune. If I still lean out then upgrade lines. I would be much happier doing the work before hand if the math adds up to requireing a new pump.

I will upgrade my wiring to ensure the pump gets as much voltage as needed.
