Car is a carbed 306, sumped tank and holley blue pump and reg for motor.

I'm having a few issues on hard accel. where the fuel press will drop to nothing before the end of the track, seems like the fuel cant keep up.

Right now it has -8 AN from the tank to the pump/filter, then -6 AN out from the pump to the reg. and -6 AN from the reg to the carb.

I was told that my -6 AN line from the pump to the motor may be to small to feed the motor at higher RPM.

thinking about upping the size of the line to -8 AN from the pump to reg but keeping the -6 to the carb.

So my question here is about the line from the tank to the pump, do I need to switch that line out to a -10 to feed the pump or can it stay the same size as the line out?

Oh and no return line is used.

thanks
