info
well i'm looking at a holly 4 bbl 750-770cfm area, fuel pump i dont know prob some high volume mechanical pump, and no more than 7000rpm max. prob only 6000rpm area, but for a pretty good length of time.
so -8 is 1/2 do they work like a shotgun? meaning bigger number smaller diam? -10=3/8?? |

Anything near 500 hp, 3/8". Depending on hp level & vehicle usage, line dia. could be as high as 1/2".

I just put a new fuel cell in my Drag car.
Everything is -8 from cell to fuel pump. Havent had it out yet. Hoping for good results. Steve |
