ok i got a 347 n/a high compression motor fully ported victor jr heads ported victor 5.0 intake custom ground CI cam 36lb injectors 90mm throttle body 3 inch exhaust but im concern now is the fuel system. i want tou run a 255lph in tank but pple are telling me its not going to be enough. also would the stock fuel lines support it? im runnin aeromotive fuel rails. what do you guys think should i sump the tank and run a external pump or run an in tank with an inline filter as well?

Is the 347 giving you issues, or are you just wanting a larger pump?

the stock fuel lines and 255lph will support enough hp to split a stock block. you wont have any problems making 500rwhp with the fuel setup you have

+1 the single intank pump is all you need....if you want you can get the high pressure 255 but its not needed.

255 pump and lines will be enough to support it, put it on a dyno and get the a/f reading when it's all ready and that'll show you what you need to know
