Fuel line ?

I need some help with my fuel system i am running an aeromotive a1000 fuelpump and am making about 650 on motor and going to spray 300 what size line will i need to run . If some one can give me a little chart on an sizes to 1/2 inch size. Something like this Thankyou

6an= ?
8an= ?
10an= ?

Wrong forum... I'll move it to fuel and ignition.

The "AN" size is approx. the line diameter in 16ths of an inch....

-6AN = 6/16 = 3/8"
-8AN = 8/16 = 1/2"
-10AN = 10/16 = 5/8"

I run 800 flywheel HP, including a 300-shot, off -6AN supply and return lines, with the rails running in parallel instead of in series. If you are looking at 950HP, you should be running at least an -8AN supply.

Note that the sizes are the eqivalent of O.D. for a steel hard line.
