Making a ton of assumptions a 35gph volume is only good for around 450 HP.
But...gph ratings on fuel pumps are often "free flow" - meaning with the outlet line open.
Lines, fittings, bends, filters, desired pressure values and such will all reduce that actual volume.
Again - lots of assumptions - the outlet side of a fuel pump line size is less critical that the inlet side size.
The inlet side is under vacuum - comparatively low.
The outlet side in under pressure which can be comparatively high.
This is why "in tank" pumps on new cars, running with high pressure, can use such small line sizing.
