at what hp would a inline fuel pump come into play or be needed?

just curriuos when would a inline fuel pump come into play or when would one be needed.. i have a walbro 255 ( i think ) but was doing some tuning witha close friend in houston and a comment came up that i am gonna need a inline at one point we thought we ran out of fuel on the dyno. the truck runs well as of now, but i asked again this weekend and it was mentioned to get one..

honestly a inline pump with a intank is a waste. if you are honestly running out of a 255 intank then you sir are well over 5xx rwhp. looking at your mods i doubt you are.

if you ever did need another pump 2 intanks are better then 1 and 1.

thats what i thought!!! plus after doing some searching and reading your answer makes more sense.

Remember also that N/A set-ups require less fuel for the same hp level
compared to Forced Induction.

FI runs much richer A/F's to help with engine cooling.
