I'm looking to get some real life numbers of high HP and fuel line size. This winter I just wanted to run 2, 1/2 hard lines for feed an return. My future HP will be a max of 800 I would say. What are you running and your HP?

Thanks

1/2" line will be fine for 800hp.

Single 10an out with 8an return 600 rwhp.

#8an supply and return.

800HP -12AN to pump -10an to Holley big port regulator and -8AN to carburetor.My system is dead headed.
Vinny

#10 to regulator and #8 return with a Aeromotive A1000 pump 680rwhp

-10 feed -8 return, 712 HP at the wheels and hope to go over 800 w/spray.;)

Aeromotive A2000 pump and A2000 regulator. 10AN from sump to filter, 10AN to pump, 10AN to regulator, 8AN return, separate 8AN to the primaries and secondaries. 850HP plus out of the motor with 10 psi boost. The Aeromotive A2000 pump is quite noisy.

I have no horsepower and run 1/2" steel braded line.

Another question...

All the sumps I'm looking at have either 3/8 or 1/2 bungs. Why would you connect a -10an line to a 1/2 bung? Wouldn't you have to use both 1/2 outlets to a Y then go into a -10an?

I had to cut the bung out of mine and weld the bigger one in its place.Or on my freinds car we used both outlets with a Y to a -10. I just read a article in Car Craft where they covered the same thing and said they wanted to ask why too. They used the Y method.
