Question What fuel system for LS7 crate?

I bought an LS7 crate engine and Iím not sure what I need in terms of fuel system. Iím going to use this fuel cell from Summit Racing:

And I was looking at this fuel system:

Is it sufficient in terms of flow and pressure for a slightly tuned 600hp LS7? Any other suggestions?

Thanks

First off what kinda car? What are you goals with the car-street/track? What mods do you plan? I can help you spec out a system for your needs.

Hi Nate,

I'm building an AC Cobra replica with an LS7 crate engine. I'm planning on a cam upgrade, headers and a cat less exhaust, some kind of cold air intake and a custom tune. So nothing radical and I expect to end up a tad above the 600hp mark. This will primarily be a street car but I might visit a track once in a while

Thanks,

I would build you a system kinda like our Stage2 Street kits A Walbro 340 mounted in your fuel tank just with complete feed and return lines, LS7 rails, Reg., Filter...You may need to add a BAP just for some safety if it goes past 600rwhp but the system would be sufficient. Unless you were planning on a fuel cell where you could take from the bottom or sump and an inline pump then we could step up the pump some.

Nate,

I have already bought a fuel cell from Summit Racing, more specifically this one:

http://store.summitracing.com/partde...5&autoview=sku

I haven't received my engine yet but I think it comes complete with rails and injectors already mounted. I'm not sure about the reg and filter but I don't think they are included.

Could you please quote me for a complete system? I'm not sure if you are allowed to post prices on here but otherwise you could do it via PM. I have no intentions on going over 600rwhp, apparently they have got around 635hp on the flywheel with this setup I'm going to use.

Thanks

Ok to retain your fuel rails and do a basic returnless system like stock. From Fuel cell to filter to inline Walbro pump to regulator to filter up to rails and a return section from reg. back to tank. $850 for good quality parts I can do a cheap version with black pushloc hose and Corvette Filter/Reg.
