Fuel delivery on high HP application. Pump questions.
First off, I'm a newb.
Second, I did search.
I tried posting this elsewhere, but maybe it was in the wrong section, so I'll try here.
I can't put all the numbers together to find out how much fuel I'll need pumping through 1000cc injectors at 8500 redline. How to figure out how much I will need to pump to maintain pressure?
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 in my honda. 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? What opening will allow what flow per minute...
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.
Please don't tell me I'll be happy with X pump; don't tell me my little honda shouldn't need more then X.
I'm asking how to calculate what pump I would be happy with... Get it?

IMO your best bet would be to get a sump, it welds on to the bottom of your factory tank. The aeromotive a1000 would be a good pump for you. When using the A1000 u will need to use big fuel line. The pump has a 10an inlet and outlet. You would run a line from the sump into to a filter then from the filter into the pump. From there it would go up toward the fuel rail going through another filter before it goes into the fuel rail. u would toss your stock FPR fuel pressure regulator. And run a line from the fuel rail to a aeromotive regulator Then back to the tank. U could make a plate that overs where the stock pump went and run your return line to that.
its getting late sorry for the confuzion

i think you need to find out what the injector manufacturer rates their fuel pressure flow at.
if they flow 1000cc@50psi (for example) then you need a pump that can flow and support a constant 50psi. if your feeding the injectors more fuel pressure then they are flowing more than advertised.
or am i wrong??
