Running out of fuel!

Im pretty much in the same boat as you are. I have a 331 stroker supercharged and Im out of fuel at 5500 RPM. I have 50lb injectors, 255 in tank pump and an Anderson Ford Big Pump inline pump. Im also running stock lines and rails. I ad my car dyno tuned at Anderson Ford and they all agree I have a fuel Volume issue. Obviously an Aeromotive kit would fix this problem, as it would fix yours to. Most guys will tell you can probably get away with just upgrading you lines and rails, but I like the assurance that everything I will need will be in the kit. Ive talked with Aeromotive before and you can either go with there internal sumped kit or external, they offer the same performance but the external mounted pump kit is cheaper yet a little louder.

Whats your budget? I would like to see lines, rails at a min, add a big external pump and you'll be good up to about 1000hp

What intake are you running, what distributor?

That combo should be ok with a 255 pump and stock lines.. Get bigger injectors..how much power is your combo making? If it's less than 500 I would get bigger injectors. Get the thing tuned, they can tell if your injectors are maxed out..
