Fuel system good enough for 525 hp?

Do you remember what type of line you used? My issue is the inner diameter of the 6AN line I want to use is smaller than most other 6AN lines due to the thickness of the ptfe core. Looking around I saw From .312 ID to .340 ID. Just don't know if it's enough to make a difference. Your info does sound encouraging. This car won't be raced at the track but do need enough fuel flow to keep from starving it the least bit at wide open throttle.
No sure on the brand but it is 6AN push loc hose.
The id of the 1/4 npt to 6AN is .29 if that helps..
