LS swap fuel pump question

[ouch]

I have on order a carbureted LS 427 from Blueprint and will need an electric fuel pump. Will a Holley Blue pump be enough? Is anyone using this successfully with no return line?

Is the engine going to use a carburetor or fuel injection? 

If carburetor, the blue pump will be fine.

If fuel injected, the blue pump will not work.

Sorry just edited. Its Holley 850.

I have used that fuel pump with my carbureted (at the time) LS6 454 engines in both my old Monte & current Z/28. No problems at all, and I also used their fuel regulator to knock down the pressure too..

Like Joe stated that pump will work with a regulator.

I would also suggest 1/2" fuel line from the tank to the carb to feed the beast if you do not have that already. 

Also a sump in the tank or the option I took for "Big Red" which is a 1/2" sending unit from RobMC that has an extension towards the back bumper. This way you can run a stock fuel tank.

Thanks. Will do the 1/2". Thanks for the "RobbMc". Spending some money there.
